Minor cleanup...

Fix `widget_draw_preview()` not taking into account given alpha.

Needed to get correct 'inactive' effect on buttons with big previews.

I18n message extractor script: py code: do not consider strings inside 'Compare' AST nodes.

Otherwise, we'd get 'MOVIE' from `text="Build Proxy / Timecode" if clip.source == 'MOVIE' else "Build Proxy")`...

Fix T44842: Modal Timer (template) should return {'CANCELLED'} when cancelled!

preview buttons: tiny optimization

Fix T44836: crash when multi-view is enabled and switching to BI rendered viewport display

Depsgraph: Avoid unnecessary char*/string conversion when creating RNAPathKey

Fix T44709: New Depsgraph not evaluating driver interactively

Issue was caused by drivers which uses component of an array as a target,
this was not handled properly in the RNA path key.

Fix T44822: python enums' itemf callback did not handle 'NULL' context case.

Enum's itemf callback can be called without context in some cases (UI, doc generation...).
Python's enum properties did not handle this at all - it's kind of odd this did not cause
more trouble and wasn't notice earlier... Probably dynamic enums using context are not
much used in py code.

Note about nodes: those are heavy users of dynamic enum with context. Now,
we expect `NodeCategory.poll()` and `NodeItem.poll()` to always be called with
a valid context (since when there is no context available, we can assume `poll()`
is always True). `NodeCategory.items()`, however, must accept NULL context, so if
you use custom `items` callable for your custom node categories, you may need
to update it (as was done here for builtin `node_group_items()`).

Fix T44815: Sound bake doesn't check filepath

Cycles: Fix compilation error of split kernel

The code was failing to compile on runtime because of some path differences,
and it seems we don't need to specify full path to the file which originally
seemed to be needed to make include directives expansion working correct.

BGE: Fix bug with default material and MTFace.

It set default material even if there are a MTface but no blender material.
Tested in GLSL and Multitexture.

Reviewers: HG1

Fix error redoing shrink fatten

Use a property to store even-offset option.

Fix bend in object mode (wasn't rotating objects)

Fix memory leak /w bend tool

Cleanup: const char for operator ID's

Fix T44833, OpenCL compile error on AMD.

This was broken after the kernel file restructure.
Variables allocated in the __local address space can only be defined
inside a __kernel function.

We probably need to solve this a bit differently once we do the CUDA
kernel split, but this fix shoud be good enough until then.

Fix T44830, wrong sample progress number when using split device.

Value was not set, moved it out of the constructor into
device_opencl_create() now.

Fix T44823: No menu entry for Circle Select in UV/Image editor.

Fix T44814: 'preview' icons would not greyout.

Since they are premultiplied, we need separated handling of colors and alpha blending
if we want additional alpha factor to work OK.
