Library reload code: add early out in case there is nothing to reload.

Try to fix pixsize in render mode

Still the pixsize is not working becaus ethe values are not valid.

DRW: Fix memory leak with dupli objects.

This was caused by dupli's ObjectEngineData that were not free.

This allocates the data using the instance data manager (no alloc/free between frames). Though the data should be treated as not persistent in this case.

DRW: Opti: Use less bytes in DRWUniform.

Clay: Small refactoring of matcap_colors and put ubos into sldata.

Ubos needed to be free correctly.
Also the matcap colors are statics and does not need to be uploaded each drawcall.

WIP: More work on render

Now get a result, but still the stroke is missing and replace any other render image.

Merge branch 'master' into blender2.8

WIP: Initial steps to define render to image functions

This commit is to put in place all components of the render, but still not working and only enabled in debug mode.

Calculate zdepth relative to camera plane if rv3d is null

If the viewport is not available, RegionView3D is null, so to calculate the z-depth must use the camera plane.

This is a preliminary step to integrate render (F12)

Update modes after changing layers or active object from python

Depsgraph: More fixes for shape keys

Made shape keys to work for meshes. Also added missing code for curves.

Curves and lattices will not have shape keys visible, since modifiers support
is still to be done for them.

Disable grease pencil paper in render mode

This is a preliminary step to integrate render (F12)

Clear scene obedit when switching view layers

Fix for mode switching objects

Depsgraph: Fix crash with shape keys and lattices

Only crash is fixed, still need to do something about missing recalc
or something like that.

Merge branch 'blender2.8' into asset-engine

Update CUEW to latest version

This brings separate initialization for libcuda and libnvrtc, which
fixes Cycles nvrtc compilation not working on build machines without
CUDA hardware available.

Depsgraph: Fix crash when visible update is called after tagging for updates

It is possible to have non-NULL scene in graph which was never built yet,
this happens when ID is tagged for update for non-built graph.

Was causing crash opening deg_anim_pose_bones.

Reported by Mai in IRC, thanks!

Make particle-edit check in cycles TODO (cycles needs some access to mode)
