The copy-to-selected operator for RNA buttons uses paths for copying
object pointer properties. Copying other ID data blocks is deliberately
disabled:
https://developer.blender.org/diffusion/B/browse/master/source/blender/editors/interface/interface_ops.c$274
However, the RNA_path_resolve_full function is not properly working for
retrieving pointer properties: it always will dereference pointer
properties in anticipation of further path elements.
In fact the return value of RNA_path_resolve_full has a conflicting
double meaning. It returns `false` when
* the RNA path is invalid
* any of the pointer properties is NULL
This means that it is not capable of returning pointer properties at all.
To make this possible, there is now an internal function for path
parsing, which returns false //only// if the the path is invalid.
On top of this there are 4 wrapper functions for retrieving either
actual property values (RNA_path_resolve, RNA_path_resolve_full) and for
retrieving pointer+property pairs (RNA_path_resolve_property,
RNA_path_resolve_property_full). The latter 2 variants will **not**
dereference pointer properties at the end of the path, so callers can
actually get the property itself. The `***_full` variants include an
array index return value.

This is a addtion to the dynamic fly mode.
It behaves as the first person navigation system available in most 3d world games nowadays.
You can alternate between the old mode (Fly) and the new mode (Walk) in User Preferences > Inputs
Manual:

http://wiki.blender.org/index.php/Doc:2.6/Manual/3D_interaction/Navigating/3D_View#View_Navigationhttp://wiki.blender.org/index.php/Doc:2.6/Manual/3D_interaction/Navigating/3D_View/Navigation_Modes
Shortcuts:
----------
WASD (hold) - Move forward/backward and straft left/right
QE (hold) - Move up and down
Tab - Alternate between Walk and Fly modes
Shift (hold) - Speed up movement
Alt (hold) - Slow down movement
Space or MMB - Teleport
V - Jump
+/- or mouse wheel - speed increase/decrease speed for this Blender session
User Preferences Options:
-------------------------
Navigation Mode - fly/walk navigation systems (fly is the old, walk is the new, next options are for walk mode only)
Gravity - alternate between free navigation and walk with gravity modes
Mouse Sensitivity - sensitivity factor to mouse influence to look around
Teleport Duration - how long the teleport lasts
Camera Height - camera height to use in gravity mode
Jump Height - maximum jump speed in m/s
Move Speed - base move speed in m/s
Boost Factor - multiplication factor when running or going slow (1/boost)
Development Notes:
------------------
* The initial code was based on view3d_fly.c.
* The NDoF code was not touched, so it most likely is not working.
Pending Issues:
---------------
* Draw in the UI the shortcut options, and current values (e.g., Mode: Fly/Walk)
(we need a proper API for that)
* OSX seems to present issues if we re-center the mouse every time. We implemented a workaround for that, but a real fix would be welcome.

For now this provides the following outputs:
- Color
- Light Vector
- Distance
- Shadow
- Visibility Factor
Note: Color output is multiplied by the lamp energy. Multiplication of
color*max(dot(light_vector,normal_vector),0)*shadow*visibility_factor
produces the exact same result as the Lambert shader.
Many thanks to Brecht for code review and discussion!
When setting keymap properties to values equalling the RNA default, they will
get "unset" and automatic operator behavior is used. There is no way to
explicitly set the default value as a user.
1) To allow distinguishing uninitialized (not set) properties in the keymap
items, a few changes to the RNA struct comparison function are needed: Instead
of allowing only strict/non-strict comparison of 2 properties A and B in a
struct, this now has 3 modes:
* STRICT: compare only the actual property values (same as 'strict' before)
* UNSET_MATCH_ANY: if either A or B is unset, consider them a match (same as
non-strict before)
* UNSET_MATCH_NONE: if one property is set and the other not, consider them a
mismatch.
The new UNSET_MATCH_NONE mode is useful for keymaps, because it allows keeping
user-defined property values in the keymap even if they match the default
property value (see wm_keymap_diff function in wm_keymap.c)
2) A new operator is added for unsetting ID properties in the RMB context menu
and in user preferences next to keymap properties. This only works on ID
properties and deletes the ID property storage, so that the default value is used.
In the user preferences for keymaps the properties are shown in an inactive
layout to indicate that the default value is used (which some operators such as
the "select linked" op from the report use to trigger automatic behavior). When
the user sets a property it gets set and stays that way until explicitly "unset"
using the new operator.
When printing operator reports, ommit unset properties.
This is needed because in some cases operators check if a value is set or not, so filling in default arguments may change behavior.
Instead of having ifdef __GNUC__ all over the headers
to use special compiler's hints use a special file where
all things like this are concentrated.
Makes code easier to follow and allows to manage special
attributes in more efficient way.
Thanks Campbell for review!
* It was not clear that RNA_parameter_length_get() & co only affected dynamic properties, renamed them to RNA_parameter_dynamic_length_get() and such.
* Fixed RNA_function_find_parameter(), we can't use BLI_findstring() here, need to call RNA_property_identifier()!
* Fixed RNA_parameter_get() and RNA_parameter_set(), which were completely wrong for dynamic properties.
* Fixed RNA_parameter_dynamic_length_get/set_data(), they did not check the property was actually a dynamic one and were using again ugly blackmagic casting intead of ParameterDynAlloc structure!
* makesrna was still using an ugly hackish (and perhaps not always working) code when handling dynamic parameters, now synchronized with RNA_parameter_dynamic_length_get_data and RNA_parameter_get code.
down, this time by the operator properties getting converted to a string for
display in the info window.
With 1000+ stroke points this can get slow, and takes up too much space anyway,
so now it's (somewhat arbitrarily) limited to printing only 10 points.
Most of the places which relied on RNA_path_resolve() did so believing that if
it returned true, that it had found a valid property, and that the returned
pointer+property combination would be what the path referred to. However, it
turns out that if the property at the end of the path turns out to be a
"pointer" property (e.g. "data" for Object.data), this would automatically
become the pointer part, while the prop part would be set to null. Hence, if a
user accidentally (or otherwise) specifies a path for the single-property driver
variable type like this, then Blender would crash.
This commit introduces two convenience functions - RNA_path_resolve_property()
and RNA_path_resolve_property_full() - which mirror/wrap the existing
RNA_path_resolve() functions. The only difference though is that these include a
check to ensure that what was found from resolving the path was in fact a
property (they only return true iff this is the case), and make it explicitly
clear in the name that this is what they will do so that there's no further
confusion. It is possible to do without these wrapper functions by doing these
checks inline, but the few cases that had been patched already were pretty
hideous looking specimens. Using these just make it clearer and simpler for all.
I've also beefed up the docs on these a bit, and changed these to using bools.
and RNA for it independent of the build flag for enabling Freestyle. Suggested
by Sergey Sharybin through a code review of the branch.
* Many #ifdef WITH_FREESTYLE blocks were removed to always have Freestyle-specific
DNA file specification and RNA for it built in Blender. This will allow Freestyle
setting survive even when a non-Freestyle build is used for loading and saving
files. It is noted that operations are still conditionally built through #ifdef
WITH_FREESTYLE blocks.
* To this end, new blenkernel files BKE_freestyle.h and intern/freestyle.c have
been added. All API functions in FRS_freestyle_config.h as well as some of those
in FRS_freestyle.h were moved to the new files. Now the relocated API functions
have BKE_ prefix instead of FRS_.
PyNodes opens up the node system in Blender to scripters and adds a number of UI-level improvements.
=== Dynamic node type registration ===
Node types can now be added at runtime, using the RNA registration mechanism from python. This enables addons such as render engines to create a complete user interface with nodes.
Examples of how such nodes can be defined can be found in my personal wiki docs atm [1] and as a script template in release/scripts/templates_py/custom_nodes.py [2].
=== Node group improvements ===
Each node editor now has a tree history of edited node groups, which allows opening and editing nested node groups. The node editor also supports pinning now, so that different spaces can be used to edit different node groups simultaneously. For more ramblings and rationale see (really old) blog post on code.blender.org [3].
The interface of node groups has been overhauled. Sockets of a node group are no longer displayed in columns on either side, but instead special input/output nodes are used to mirror group sockets inside a node tree. This solves the problem of long node lines in groups and allows more adaptable node layout. Internal sockets can be exposed from a group by either connecting to the extension sockets in input/output nodes (shown as empty circle) or by adding sockets from the node property bar in the "Interface" panel. Further details such as the socket name can also be changed there.

Resolved conflicts:

Also updated source/blender/blenkernel/intern/linestyle.c as a follow-up of
recent changes for the use of bool.
This is just the basic structure, the simulation isn't hooked up yet.
Scenes get a pointer to a rigid body world that holds rigid body objects.
Objects get a pointer to a rigdid body object.
Both rigid body world and objects aren't used directly in the simulation
and only hold information to create the actual physics objects.
Physics objects are created when rigid body objects are validated.
In order to keep blender and bullet objects in sync care has to be taken
to either call appropriate set functions or flag objects for validation.

This was difficult to do because we group theme colours and display them
together in user preferences. To make the background options more
presentable and keep them grouped and separate, I needed to group the
two gradient colours somehow. I added a separate ThemeSpaceGradient RNA
struct as opposed to ThemeSpaceGeneric. This struct is the same as
ThemeSpaceGeneric but it lacks the window background option (which does
nothing now) and includes the UiGradient struct which now has both
gradient colours. I modified the clear functions to use a new high
colour from the gradient. Now all options appear grouped and any other
editor that may use a gradient for the window background may do so.
Also corrected incorrect MAIN_VERSION_ATLEAST macro, it would not detect
versions correctly
It introduces a new (py-extendable and registrable) RNA type, UIList (roughly similar to Panel one), which currently contains only "standard" list's scroll pos and size (but may be expended to include e.g. some filtering data, etc.). This now makes lists completely independent from Panels!
This UIList has a draw_item callback which allows to customize items' drawing from python, that all addons can now use. Incidentally, this also greatly simplifies the C code of this widget, as we do not code any "special case" here anymore!
To make all this work, other changes were also necessary:
* Now all buttons (uiBut struct) have a 'custom_data' void pointer, used currently to store the uiList struct associated with a given uiLayoutListBox.
* DynamicPaintSurface now exposes a new bool, use_color_preview (readonly), saying whether that surface has some 3D view preview data or not.
* UILayout class has now four new (static) functions, to get the actual icon of any RNA object (important e.g. with materials or textures), and to get an enum item's UI name, description and icon.
* UILayout's label() func now takes an optional 'icon_value' integer parameter, which if not zero will override the 'icon' one (mandatory to use "custom" icons as generated for material/texture/... previews).
Note: not sure whether we should add that one to all UILayout's prop funcs?
Note: will update addons using template list asap.
This two things were using the same DNA and RNA structures because
internally they're completely the same. However, that was confusing
from the interface point of view.
Now it should be much more clear what's going on there.
New Outliner mode: "Main Data".
This shows a flattened, non-hierarchical list of all linkable "ID" data in
your current project. It works fine on searches. Actually this is the
view on the "Main" database in Blender, the one that's saved in a .blend.
This is in general more useful than the "Datablocks" viewer,
which is not searchable, and shows every property of data as well.
Based on patch [#30837] UV Offset Modifier
by Pawel Kowal (pkowal)
- Allows you to setup a transformation between objects to apply to UV coords.
- Option to select which axis apply to U/V.
- Option to select the UV center (needed for transformations that scale or rotate).
- Uses from/to objects in a similar way to the Warp modifier.
- Vertex group can be used to adjust influence.
