This changes BKE's fitting code to use `BKE_camera_params_compute_viewplane` instead of
`BKE_camera_view_frame`. This allows that code to work with orthographic projection too.
Also, two funcs were added to rna's Object, to resp. get the projection matrix of that
object (mostly useful for cameras and lamps objects), and return position this object
should be to see all (to fit) a given set of points.

The getter of this matrix (actually, `BKE_object_matrix_local_get()`) was only correct
in case of pure-object parenting, bone parenting and such did not gave valid results.
Also cleaned up a bit setter code, was using as temp storage ob->obmat itself,
which is supposed to be a world matrix!

This merge-commit brings in a number of new features and workflow/UI improvements for
working with Grease Pencil. While these were originally targetted at improving
the workflow for creating 3D storyboards in Blender using the Grease Pencil,
many of these changes should also prove useful in other workflows too.
The main highlights here are:
1) It is now possible to edit Grease Pencil strokes
- Use D Tab, or toggle the "Enable Editing" toggles in the Toolbar/Properties regions
to enter "Stroke Edit Mode". In this mode, many common editing tools will
operate on Grease Pencil stroke points instead.
- Tools implemented include Select, Select All/Border/Circle/Linked/More/Less,
Grab, Rotate, Scale, Bend, Shear, To Sphere, Mirror, Duplicate, Delete.
- Proportional Editing works when using the transform tools
2) Grease Pencil stroke settings can now be animated
NOTE: Currently drivers don't work, but if time allows, this may still be
added before the release.
3) Strokes can be drawn with "filled" interiors, using a separate set of
colour/opacity settings to the ones used for the lines themselves.
This makes use of OpenGL filled polys, which has the limitation of only
being able to fill convex shapes. Some artifacts may be visible on concave
shapes (e.g. pacman's mouth will be overdrawn)
4) "Volumetric Strokes" - An alternative drawing technique for stroke drawing
has been added which draws strokes as a series of screen-aligned discs.
While this was originally a partial experimental technique at getting better
quality 3D lines, the effects possible using this technique were interesting
enough to warrant making this a dedicated feature. Best results when partial
opacity and large stroke widths are used.
5) Improved Onion Skinning Support
- Different colours can be selected for the before/after ghosts. To do so,
enable the "colour wheel" toggle beside the Onion Skinning toggle, and set
the colours accordingly.
- Different numbers of ghosts can be shown before/after the current frame
6) Grease Pencil datablocks are now attached to the scene by default instead of
the active object.
- For a long time, the object-attachment has proved to be quite problematic
for users to keep track of. Now that this is done at scene level, it is
easier for most users to use.
- An exception for old files (and for any addons which may benefit from object
attachment instead), is that if the active object has a Grease Pencil datablock,
that will be used instead.
- It is not currently possible to choose object-attachment from the UI, but
it is simple to do this from the console instead, by doing:
context.active_object.grease_pencil = bpy.data.grease_pencil["blah"]
7) Various UI Cleanups
- The layers UI has been cleaned up to use a list instead of the nested-panels
design. Apart from saving space, this is also much nicer to look at now.
- The UI code is now all defined in Python. To support this, it has been necessary
to add some new context properties to make it easier to access these settings.
e.g. "gpencil_data" for the datablock
"active_gpencil_layer" and "active_gpencil_frame" for active data,
"editable_gpencil_strokes" for the strokes that can be edited
- The "stroke placement/alignment" settings (previously "Drawing Settings" at the
bottom of the Grease Pencil panel in the Properties Region) is now located in
the toolbar. These were more toolsettings than properties for how GPencil got drawn.
- "Use Sketching Sessions" has been renamed "Continuous Drawing", as per a
suggestion for an earlier discussion on developer.blender.org
- By default, the painting operator will wait for a mouse button to be pressed
before it starts creating the stroke. This is to make it easier to include
this operator in various toolbars/menus/etc. To get it immediately starting
(as when you hold down DKEy to draw), set "wait_for_input" to False.
- GPencil Layers can be rearranged in the "Grease Pencil" mode of the Action Editor
- Toolbar panels have been added to all the other editors which support these.
8) Pie menus for quick-access to tools
A set of experimental pie menus has been included for quick access to many
tools and settings. It is not necessary to use these to get things done,
but they have been designed to help make certain common tasks easier.
- Ctrl-D = The main pie menu. Reveals tools in a context sensitive and
spatially stable manner.
- D Q = "Quick Settings" pie. This allows quick access to the active
layer's settings. Notably, colours, thickness, and turning
onion skinning on/off.
Along with some minor cleanup and simplifications.

too crowded.
UVs in the same layer can be used for many images. It used to be
possible to filter UV faces based on the image, but this is impossible
now due to the way the system works, so I added an option to allow
filtering UVs based on active material index.
Rationale on using option and not being smart here (options are bad tm)
is that for some workflows, such as preserving image space by using the
same image for many materials, people might want to turn this off.
This commit merges the code in the pie-menu branch.
As per decisions taken the last few days, there are no pie menus
included and there will be an official add-on including overrides of
some keys with pie menus. However, people will now be able to use the
new code in python.

Thanks:
Campbell Barton, Dalai Felinto and Ton Roosendaal for the code review
and design comments
Jonathan Williamson, Pawel Lyczkowski, Pablo Vazquez among others for
suggestions during the development.
Special Thanks to Sean Olson, for his support, suggestions, testing and
merciless bugging so that I would finish the pie menu code. Without him
we wouldn't be here. Also to the rest of the developers of the original
python add-on, Patrick Moore and Dan Eicher and finally to Matt Ebb, who
did the research and first implementation and whose code I used to get
started.
The previous fix 162d6c73e3 has been cancelled because it caused a
problem that mesh deform cages and so on mess up the preview. To avoid
the problem, viewport doesn't show mesh object if its draw type is
bounding box or wireframe.

This was storing the original object matrix, which builds on the
assumption that obmat is modified during dupli construction, which is a
bad hack.
Now the obmats are still modified, but this only happens outside of the
dupli system itself and the original ("omat") is stored as local
variables in the same place where the obmat manipulation takes place.
This is easier to follow and avoids hidden hacks as much as possible.

Levels of detail can be added and modified in the object panel. The object
panel also contains new tools for generating levels of detail, setting up
levels of detail based on object names (useful for importing), and
clearing an object's level of detail settings. This is meant as a game
engine feature, though the level of details settings can be previewed in
the viewport.

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!
curve children of a triangle vertex parent would only display their relationship line to the first vertex. (confusing)
also added OB_TYPE_SUPPORT_PARVERT macro.
flush the selection on entering editmode instead (since the selection mode can be changed with another mesh).
is other tools leave the selection incorrectly flushed, those will need to be fixed so transform works as expected.
Fix turned out to remove as much "manual UI" from 3D view header as possible. Mode selector and all transform manipulators/orientations stuff are now RNA-based UI (leaving basically only edit mesh select modes with custom handlers, as they have some quite specific features).
To achieve this, four main modifications were done:
* enum-operator-generated menus are now MENU (i.e. dropdown lists) in headers too.
* All bit-flag enums expanded in ROW buttons now have a handling consistent with e.g. layers, or what we already have for transform manipulators, i.e. clicking select only one element, shift-click to select multiple ones.
* Consequently, the three RNA booleans manipulators flags are merged into a single bit-flag enum (yes, this is also an API change, though I doubt many scripts use it).
* Now the width of enum-based dropdown lists is computed from longest item name in enum, no more from a dummy place holder string (when no label/name is given).
All this allows to remove some code from 3DView/transform areas, that was actually mostly duplicating RNA/operator one.
Also done a few optimizations here and there (among others, do not pass &numitems to RNA_property_enum_items() when you do not need it, saves at least an iteration over enum items to count them).
Many thanks to Brecht for the reviews!
