fix shaders for picky GLSL compilers

@zeauro reported this issue:
texture2DRect needs the ARB_texture_rectangle extension.
But isn't that an OpenGL 2.1 feature and should be part of GLSL 1.2+?

This should fix it, and future shaders should do something similar.

Cycles: Split device_opencl.cpp into multiple files for easier maintenance

There are no user-visible changes, just some internal restructuring.

Fix T49609: Point density textures: vertex colors are not properly averaged in BI

Nice to have in 2.78a, though not a regression.

CMake changes for new macOS target 10.9 / libc++ libraries.

Gawain: validate inputs to add_attrib

Should help prevent errors when building vertex formats.

Ammend to rB00dc0666b3fe: forgot to fix boid->ground of first particle.

This code is confusing, such dirty details should not sneak out of
particles' own private code. :(

Fix T49608: runtime-only particle's boid->ground Object pointer was left dangling to invalid value in read code...

Fix a few compile errors with C++11 on macOS.

BLI_task: fix case were some pool could work in more threads than allowed.

We were checking for number of tasks from given pool already active, and
then atomically increasing it if allowed - this is not correct, number
could be increased by another thread between check and atomic op!

Atomic primitives are nice, but you must be very careful with *how* you
use them... Now we atomically increase counter, check result, and if we
end up over max value, abort and decrease counter again.

Spotted by Sergey, thanks!

OpenGL: fix smooth point fringe

Smooth edge was fading to transparent black instead of transparent color. My bad.

OpenGL: draw f-curve points and handles with new imm mode

Got rid of GLU and some matrix manipulation. Everything is shader driven now, drawn with point sprites.

Still plenty to do in this file...

Part of T49042 and T49043

OpenGL: shaders for smooth round points

Solid color with an optional outline.

size (diameter) and outlineWidth are in pixels.

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!

draw region emboss with new immediate mode

Simple convert of drawing emboss lines to new immediate mode.

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.

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.
