UI: better widget drawing with thick line width.

When the line width was larger than the UI scale, there was not enough
space for thicker widget outlines to draw properly. Now widgets are made
a little larger to accommodate the thicker outlines.

UI: improve corner splitting feedback by showing custom cursors.

* Two cursors for horizontal and vertical split.
* Four cursors for each join direction.
* One cursor to indicate when splitting is not possible.

UI: increase corner splitting hit area to include screen edges.

makesrna: Fix windows build.

makesrna requires the pthread dll to be available before it can run.

Fix T60646: From instancer texture coordinate doesn't work in viewport

Made it so that generated coordinate is always calculated.

Ideally, it will only be done depending on a current shading,
but code is quite deep, and doing smarter thing here will end
up in way bigger refactor.

First, make things working, and then make them fast if they
pop up in a profiles.

Fix T61810: Cycles OpenCL denoising broken after recent changes.

Cycles OpenCL: Motion Blur Compile Directives

When using preview rendering through a camera or final rendering
the `scene.render.use_motion_blur` was not respected when building
the compile directives.

This patch will when building the compile directives check if
motion blur is enabled at all. This should lead to more efficient
kernels when no motion blur is needed.

Fix for Fix (c) T61787: Duplicating a collection instance does not duplicate the dupli_group.

Wrong logic in bitflags handling in own previous commit...

Fix (unreported) Broken DataTransfer modifier when source object is in Edit mode.

Just use common API func to get evaluated mesh of other object in
modifiers, instead of doing our own cooking. ;)

Fix T61787: Duplicating a collection instance does not duplicate the dupli_group.

Transfomr init code called just after duplication (presumably before
regular depsgraph update is executed) would erase new objects'
transflags.

This is more like a hack than a real fix, but since that transform piece
of code is already a hack... Other solution would have been to force DEG
to run after object duplication, think it's better to go with that
solution for now.

Not to mention to fact that dupli flags are put into transflag... ;)

Cleanup: typos in comments.

Fix T59338: Blender crashes immediately after loading attached file in ~80% of my attempts.

Issue was a concurrent modification of an evaluated mesh by two
other meshes using it as source for custom normals data transfer.

Note that this fixes the crash (modifiers are strictly forbidden to modify
any data besides their own!), but now will have to add a new CD type to
be able to specifically request 'computed' clnors data layer, and not
only 'encoded' one, for source mesh...

Fix T61802: EXR preview JPEGs don't have the correct color

Missing color management, probably from the very beginnings of
the OCIO integration.

Subdiv: Enable topology cache for animation

This commit makes it so both Subdivision Surface and Multiresolution
modifiers are caching OpenSubdiv topology. This cuts down evaluation
time quite a bit, especially for meshes which don't have many extra
ordinary verticies.

Only working for animation. Other modifications like edit mode needs
more work to make topology cache preserved by copy-on-write.

Fix: Missing closing brackets in include

Fix T61733: wrong alpha for sequencer screen, multiply, .. blend modes.

It was copying the alpha from the foreground instead of background image,
which is not usually what is needed and inconsistent with the compositor.

Fix T61791: Motion path step is not taken into account

Fix T61786: local view not exiting correctly after recent changes.
