Gawain: allow immBeginAtMost, immEnd with no vertices

The whole point of BeginAtMost is to avoid counting before drawing. Sometimes the uncounted count is zero, and that's ok!

Gawain: code cleanup & inline docs

Made function categories more clear & added more notes about how to use this API.

immEndVertex is no longer part of the public API.

Minor cleanup & organizing of recent additions.

another minor tweak for transform issue

Move inline function defines into own source file

Merge branch 'master' into temp_localview_split

fix for dynafrac, disallow passive objects as triggers again (to avoid the ground being a trigger)

further attempt to fix / get the transform issues under control with dynafrac

Blender 2.8: OpenGL: replace old GL with the new immediate API in UI_draw_roundbox_gl_mode

I change UI_draw_roundbox_gl_mode to use immediate API.
The rest of the change is the call to the function.
I also make some change in UI_ThemeColor4(int colorid) for eg to make convenience to use.
I would really like to know if it's the good way to do, if yes I will make all the change in the node_daw.c after, else say me what's wrong and how to deal with color else.

Collision: skip expensive BVH update if the collider doesn't move.

Since the collision modifier cannot be disabled, it causes a constant
hit on the viewport animation playback FPS. Most of this overhead can
be automatically removed in the case when the collider is static.

The updates are only skipped when the collider was stationary during
the preceding update as well, so the state is stored in a field.
Knowing that the collider is static can also be used to disable similar
BVH updates for substeps in the actual cloth simulation code.

fix grid floor drawing assert

@dfelinto reported crash when setting grid subdivisions too low.

Code was setting color twice and Gawain was catching this. Fix is to only set regular grid color when we have regular grid lines to draw. Then emphasized grid lines are free to set their own color further down.

OpenGL render: Limit number of scheduled frames for write

Previously if the rendering is much faster than saving (for example,
when transcoding stuff via VSE) it was possible to have 100s of frames
in memory.

This isn't ideal because of limited amount of RAM, so need to have
some sort of limit. This is exactly what is implemented in this commit.

OpenGL render: Fix non-deterministic order of frame writes for movies

By the design of task scheduler it was possible that tasks from somewhere
in the middle of scheduled list will be handled first.

For example, one thread might be iterating over the scheduled list and
ignore tasks because there is other thread is working on task from the
same pool. However, if that other thread finishes task before iteration
is over current thread will pick up task from somewhere in in the middle
of the list.

This isn't a problem in general case, but for movie rendering we do need
to have strict order of frames.

Custom Manipulators Core Backend

This commit lands the core backend of the Custom Manipulators project onto the blender2.8 branch. It is a generic backend for managinig interactive on-screen controls that can be integrated into any 2D or 3D edito. It's also already integrated into the window-manager and editor code where needed.

NOTE: The changes here should not be visible for users at all. It's really just a back-end patch. Neither does this include any RNA or Python integration.

Of course, there's still lots of work ahead for custom manipulators, but this is a big milestone. WIP code that actually uses this backend can be found in the 'custom-manipulators' branch (previously called 'wiggly-widgets').

The work here isn't completely my own, all the initial work was done by @Antony Riakiotakis (psy-fi) and - although it has changed a lot since them - it's still the same in essence. He definitely deserves a big credit! Some changes in this patch were also done by @Campbell Barton (campbellbarton). Thank you guys!
