Collections: API to select all scene collection objects

Select Grouped: Collection Part I

Use Shift+G > Collection. If there is only one collection, it just selects it,
if there are multiple ones user get to pick which one to select.

This is the same behaviour we have for groups. Note, we only select objects
directly in the collection, not the ones in any nested collection.

Feature suggested by Pablo Vazquez (venomgfx)

Fix typo in outliner Select Objects tooltip

Collections: API to get collection from index

Collections: API to check if object is in collection

PyDoc: Merge manual docs for bge.texture

https://docs.blender.org/manual/en/dev/game_engine/python_api/videotexture.html

Had a few things that this file did not while this file having things the other did not.
To fix, I merged both documents into the python api.

BLF: Reduce the size of the buffer requested to IMM.

There is no point to not call strlen if the number of char is large.

BLF: Perf: Divide by 6 the amount of verts sent to the GPU.

This means smaller imm buffer usage.

This does not reduce the number of drawcalls.

This uses geometry shader which is slow for the GPU but given we are really
CPU bound on this case, it should not matter.

A perfect implementation would:
- Set the glyph coord in a bufferTexture and just send the glyph ID to the
GPU to read the bufferTexture.
- Use GWN_draw_primitive and draw 2*strllen triangle and just retrieve the
glyph ID and color based on gl_VertexID / 6.
- Stream fixed size buffer that the Driver can discard quickly but this is
the same as improving IMM directly.

GWN: Add immVertex4f.

PyDocs: Adde link to Wikipedia page for mathutils.Euler class

This update adds a link to the Wikipedia article "Euler angles" to the description of the mathutils.Euler class.
I initially was not sure what a "Euler" represented in Blender API, but found the Wikipedia article helpful. I believe others will find the link helpful too if it appears in the class documentation.

This is similar to the Wikipedia links that appear in the mathutils.Matrix class, e.g: https://docs.blender.org/api/blender_python_api_current/mathutils.html?highlight=euler#mathutils.Matrix.adjugate

Cleanup: Use uppercase UI_ prefix for external functions

Using uppercase prefixes is our convention for external functions.
"External" as in functions exposed to the outside of interface/ directory.

Fix Blenderplayer compile error

UI: Fix out of bound read catched by asan.

UI: Perf: Group fill/border/emboss batches together.

This roughly halves the number of drawcalls from widgetbase_draw.

Merge remote-tracking branch 'origin/master' into blender2.8

Fix for T54437: Sequencer preview uses last updated scene

The fix started in master, moving EvaluationContext initialization
before we leave `deg_evaluate_on_refresh()`.

Upon merging master we can fix the actual issue which was to set
the EvaluationContext depsgraph even if the depsgraph was already updated.

Merge commit 'origin/master^' into blender2.8

Depsgraph: initialize EvaluationContext even if nothing to update

This is required to T54437 (sequencer preview uses last updated scene).
Although the fix itself needs to be in 2.8, for the 2.8 specific
initialization code.

UI: Perf: widgetbase: Replace imm usage by a batch cache.

Introduce a UI batch cache. For the moment it's only used by widgetbase so
leaving it interface_widgets.c. If it grows, it can have its own file.

Like all preset batches (batches used by UI context), vaos must be refreshed
each time a new window context is binded.

This still does 3 GWN_batch_draw in the worst cases but at least it does
not use the IMM api.

I will continue and batch the 3 calls together since we are really CPU
bound, so shader complexity does not really matters.

I cannot spot any difference on all the widgets I could test. I did not use
any unit tests so I cannot tell if there is really any defects.

This is not a complete rewrite but it adresses the top bottleneck found
after a profilling session.

GPUShader: Add specialized widget base shader.

This vertex shader let us draw widgets with batches instead of imm calls.
