While drawing nice 'rounded' values is OK also for 'low precision'
editing like dragging and such, it's quite an issue when you type in a
precise value, validate, edit again the value, and find a rounded
version of it instead of what you typed in!
So now, *only when entering textedit of num buttons*, we always get the highest
reasonable precision for floats (and use exponential notation when
values are too low or too high, to avoid tremendous amounts of zero's).
This commit brings some long requested improvements to the workflow for setting up
drivers, which should make it easier and faster to set up new drivers in a more
interactive fashion.
The new workflow is as follows:
1) Hover over the property (e.g. "Lamp Energy" or "Y Location") or properties ("Rotation")
you wish to add drivers to. We'll refer to this as the "destination"
2) Ctrl-D to active the new "Add Drivers" eyedropper
3) Click on the property you want to use as the source/target. The property under the
mouse will be used to drive the property you invoked Ctrl-D on.
For example, to drive the X, Y, and Z location of the Cube using the Y Location of the Lamp,
hover over any of the X/Y/Z location buttons, hit Ctrl-D, then click on the Y-Location
button of the Lamp object. Drivers will be added to the X, Y, and Z Location properties
of the Cube; each driver will have a single variable, which uses the Y-Location Transform
Channel of the Lamp.
Tips:
- Transform properties will automatically create "Transform Channel" driver variables.
Everything else will use "Single Property" ones
- Due to the way that Blender's UI Context works, you'll need two Properties Panel instances
open (and to have pinned one of the two to show the properties for the unselected
object). It's slightly clunky, but necessary for implementing a workflow like this,
as the UI cannot be manipulated while using eyedroppers to pick data.
- The eyedropper operator implemented here actually has three modes of operation.
1) The "1-N" (one to many) mode is the default used for Ctrl-D, and "Add Driver to All"
in the RMB Menu. This is the behaviour described above.
2) There's also a "1-1" (one to one) mode that is used for the "Add Single Driver" in the
RMB Menu.
3) Finally, there's the "N-N" mode (many to many), which isn't currently exposed.
The point of this is to allow mapping XYZ to XYZ elementwise (i.e. direct copying)
which is useful for things like locations, rotations, scaling, and colours.
Implementation Notes:
- The bulk of the driver adding logic is in editors/animation/drivers.c, where most of
the Driver UI operators and tools are defined
- The property eyedropper code is in interface_eyedropper.c along with all the other
eyedroppers (even though they don't share much actual code in common). However, this
turns out to be necessary, as we can't get access to many of the low-level buttons API's
otherwise.
Todo:
- It may be necessary to restore a way to access the old behaviour (i.e. "manual setup")
in case it is not practical to immediately pick a property.
- Other things to investigate here include extra hotkeys (e.g. Ctrl-Shift-D for Add Single?),
and to expose the N-N mode.
- Other things we could try include interactively applying scaling factors, picking
multiple targets (e.g. for location difference and rotation difference drivers),
and/or other ways of using these property picking methods.
Displaying a button would clamp the value if the button was outside the range.
This could be OK in some cases,
however it's problematic with object dimensions which would re-scale objects on showing the panel.
Add `ui_but_update_edited` when its OK to modify the value.
Now a 'More' item is added to the pie when there are too many items. It opens a sub-pie that contains the remaining items.
Note that this only touches operator-enum pies (like the object mode pie is), it is not a complete support for pies with more than 8 items. For this further design and code work would be needed, but this is too urgent to wait for that.
This is a better fix for T46973, should definitely be applied for 2.77 release.
Patch D1800 by myself with some edits by @campbellbarton, thanks!
RNA could define strings as dynamically sized,
but the interface ignored this and clamped them to UI_MAX_DRAW_STR.
Fixes T46734, also fixes possible pasting non-utf8 text into utf8 buttons.
This new code fixes a tons of issues with previous one, which basically was epic-failing
in many non-basic cases (especially mixed columns and rows with column-dominant layout).
It basically no more relies over order of buttons declaration in the uiBlock, instead it
finds and stores spatial neighbors and uses that data to compute needed stitching.
See code comments for details.
New code seems to be roughly ten times slower than old one (for complex grouped layouts),
that is, about a few microsecconds per alignment group - this remains reasonable.
Also, ui-align code becomming rather big in itself, it was separated in
own new `interface_align.c` file.

Now, ctrl+wheel for cycling tabs is passed to hovered button if it supports cycling values (RNA menus, color/row/number/slider buttons, list boxes)
This might feel a bit glitchy if ctrl+wheel is used to cycle tabs and in newly opened tab, a button with cycling support is under the mouse, which will get mouse input from this point on instead of region. Think this is still better than old behavior.
For popup interactions we need to know if events are in the region or not,
however subtracting the shadow isn't so reliable, since its not always added to all sides of a popup.
Instead, get the winrct value from a popup using the block rect, otherwise the winrct as-is.
This commit mainly:
* Exposes PreviewImage struct in RNA, including ways for user to set images data.
* Adds a new kind of PreviewImage, using a file path and IMB_thumb to get image.
* Adds a new kind of custom icon using PreviewImage, unrelated to ID previews system.
* Adds a python API (utils.previews) to allow python scripts to access those custom previews/icons.
Note that loading image from files' thumbnails is done when needed (deferred loading), not
when defining the custom preview/icon.
WARNING: for release addons who would want to use this, please keep it to a strict minimum, really needed level.
We do not want our UI to explode under hundreds of different flashy icons!

In addition to the unlink icon to clear a value,
When cleared, show an eyedropper to select objects or object-data
(was already available via the EKey).
When defined, uiBut->tip_func is called when button's tip is generated. This allows
for advanced, dynamic generation of tooltips.
For now, only used by UIList, which can now optionaly use a given string property
of each item for its tooltip.
Thanks to Campbell for the reviews!
Currently this is mainly useful for picking camera DOF depth.
- EKey over a distance field prompts you to pick a depth from the camera.
- WKey (Specials menu) to pick from the 3D view (when the active camera's selected).

We are still not finished, as this is only the first part of the
implementaion, but there's more to come!
Make the UI API more consistent and reduce confusion with some naming.
mainly:
- API function calls
- enum values
some internal static functions have been left for now
Decouple color picker hsv data from the whole block. Basically, each
color picker now takes care of creating its own color picker role. For
this bug report it can be seen that probably HSV is not the best space
for gamma/lift/gain workflow because it is bounded at 1.0 but this is a
separate issue.
* Only use last key for pies if it hasn't been released already
* Confirm threshold is now measured as distance after regular threshold.
zero disables.
* Only display the confirm threshold if there's a valid direction (mouse
is after threshold).
* Calculate confirm threshold taking recentering into account
