If the triangulated mesh was in itself a new mesh that should be freed this
should happen before the function returns (as it only returns a single mesh,
and thus the caller can only free one).
Add 'missing' bpy code from BKE_libblock_free_ex(), now both functions
do exactly the same thing, only the later is less flexible (fewer
'exotic' behaviors supported, like handling IDs outside of bmain etc.).
Next step: nuke usages of BKE_libblock_free functions, makes no sense to
have twice the same code around!
The issue is that the edge fix geometry goes on top of the actual drawn
points.
This commit reduce the edge fix size to the strict minimum but does not
get rid of it.

Before this Blender always needed the Wintab driver. This adds support for the
native pressure API in Windows 8+, making it possible to get pressure sensitivity
on e.g. Microsoft Surface hardware without any extra drivers.
By default Blender will automatically use Wintab if available, and if not use
Windows Ink instead. There is also a new user preference to explicitly specify
which API to use if automatic detection fails.
Fixes T57869: no pressure sensitivity with Surface pen or laptop.
Code by Christopher Peerman with some tweaks by Brecht Van Lommel.

Base outline is 2px wide (because of how we detect them).
And since inflating this outline will only produce outlines that are 2*x
thick we map the UI scalling and the outline width setting to the closest
match.
Do note that thicker outlines have a performance cost since they need more
texture fetches and passes.
This fixes T60252 3D View Outline Width not working
The existing Add and Multiply blending modes have limited usability,
because the appropriate operation for meaningfully combining values
depends on the channel. This adds a new mode that chooses the operation
automatically based on property settings:
- Axis+Angle channels are summed, effectively averaging the
axis, but adding up the angle. Default is forced to 0.
- Quaternion channels use quaternion multiplication:
result = prev * value ^ influence
- Scale-like multiplicative channels use multiplication:
result = prev * (value / default) ^ influence
- Other channels use addition:
result = prev + (value - default) * influence
Inclusion of default in the computation ensures that combining
keyframed default values of properties keeps the default state,
even if the default isn't 0 or 1.
Strips with this mode can be keyframed normally in Tweak mode,
except that for quaternion rotation keyframing always inserts
all 4 channels, and the channel value sliders on the left side
of Graph/Action editors won't insert keys without Auto Key.
Quaternion keys are also automatically normalized.
Differential Revision: https://developer.blender.org/D4190
Supporting a strip blending type that treats quaternions as a unit
also means being able to adjust all sub-channels as a unit when
inserting keyframes. This requires refactoring keyframe insertion
code to retrieve array property values for all channels at once,
before iterating over the indices being inserted.
