Eevee: Transparency: Add object center Z sorting.

Better algo should take bounding box center, but it's not referenced yet in the draw call and cannot be tweaked by user.

Eevee: Transparency: Add Alpha Blend mode.

DRW: Make Additive blending alpha premult.

Eevee: Transparency: Add support for blend ADD and MULTIPLY.

This introduces a new transparency pass.
It bypass the radial distance encoding in alpha for the transparent shaders.

DRW: Add shading group state disable.

This is a way to remove some state flag per Shading Group.

Eevee: Material: Code cleanup in order to add transparency support.

Eevee: Add support for Alpha clip and Hashed Alpha transparency.

Hashed Alpha transparency offers a noisy output but has the benefit of being correctly ordered. Noise can be attenuated with Multisampling / AntiAliasing.

Cycles: Disable OpenCL clFlush workarounds

This is something which was reported to work fine by Mai, Benjamin and
confirmed by myself. Disabling this workaround gains us some speedup:

Before Now
bmw27 04:28.42 04:07.79
classroom 09:26.48 08:54.53
fishy_cat 08:44.01 08:18.70
koro 09:17.98 08:57.18
pavillon_barcelone 12:26.64 11:52.81

Test environment is:
- Ubuntu 16.04, with all updates installed
- AMD RX 480 GPU
- amdgpu pro driver version 17.10-450821

Theme Flatty Light

Color GraphEditor tabs, brighter 3D viewport gradient

Fix memory leak caused by node clipboard

The issue was caused by combination of following factors:

- Clipboard cleanup function will pass node tree as NULL to node free
function.

This is fine on it's own, we don't have tree in clipboard.

- Node free function will call node storage cleanup only when there is
a non-NULL node tree.

This is somewhat weird, because storage cleanup does not take node
tree as argument.

So the solution here: move node storage cleanup outside of check that
node tree is not NULL.

Opensubdiv: Fix compilation error with older Opensubdiv versions

Fix T49034: multi-drag crashes when UI forces exit

Lamps should not have their own gpu material

This was leading to multiple crashes when freeing the lamps or
materials when opening old files.

Resolve T51745: Mesh extrude keep-orig needs edges

Fix T51761: wpaint select depth limit fails

Limit select fails with circle and border select.

Regression in 2.76

Fix (unreported) broken uvsculpt in Scene's toolsettings' copying.

This was serious bug actually, probably a crasher in case you free
original or copy after duplication...

Fix (unreported) Scene's copying toolsettings' clone and canvas, and particles' scene and object pointers.

imapaint's clone and canvas are refcounting Image usages.

And particle's editsettings' object and scene seem to be pure runtime
data (they are reset to NULL in readcode), so resetting them to NULL
here as well.

Fix strict compiler warning
