Merge branch 'blender2.8' into workspaces

Gawain : Added Batch_init()

to init a batch without allocating memory

Added support for correct Oculus DK1 and DK2 shaders with additional Generic shader (which could/should work for most other HMD's)
Shaders can be changed in options so you can pick a shader that matches your device

Use OBACT_NEW to show the object edit mode

De-duplicate min/max calculation in F-Curve normalization

OpenGL immediate mode: interface_draw.c (end)

Eradicate leftover legacy functions.
Fix a crash with histogram resolution.

Cycles Denoising: Remove support for cross-frame denoising

Cycles Denoising: Revert all changes to Cycles Standalone

Cycles Denoising: Enable floating point exceptions in filter code if enabled in CMake

OpenGL immediate mode: interface_draw.c (cont)

ui_draw_but_TRACKPREVIEW

Changed stipple shader usage to a bunch of GL_LINES with flat color

Complete immUniform functions to support 2float and 3float

Fixed small oops with copy paste

Fixed HMD branch for current master

Merge branch 'master' of git.blender.org:blender into HMD_viewport

OpenGL immediate mode: Added replacement for glaDrawPixelsTex_*

CTests: Initial work to cover Cycles nodes with OpenGL tests

Works similar to regular Cycles tests, just does OpenGL render to
get output image.

Seems to work fine with the only funny effect: Blender window will
pop up for each of the tests. This is current limitation of our
OpenGL context. Might be changed in the future.

Cleanup: Trailing whitespace

Cycles: Cleanup, move EdgeMap to blender_util

it's better place for such an utility structure. Still not fully ideal tho.

Cycles: Make an utility class for edge map

Simplifies some logic.

Cycles: Fix pointiness attribute giving wrong results with autosplit

Basically made the algorithm to handle vertices with the same coordinate
as a single vertex.
