UVEdit: Port texpaint_loop_wire to batch request

This removes code duplication and put an end to the old "create at request"
batch creation.

Also it uses the same vbo as the uv layer used for shading. Reducing VRAM
usage.

Also fixes the modified uv display in uv edit mode.

UVEdit: Add back uv angle stretch aspect correction

This is now done in shader so that the batches are shared across ImageUV
areas.

UVEdit: Port batches to batch request

This is in order to allow more spaces to have their batches created at the
same time and sharing the batches.

This is part of the effort fo making the drawing code more optimized. This
commit however should not introduce any difference.

This commit bypass the aspect ratio correction for angle stretch display
but this should be fixed in the next commit.

WM: Use draw manager to draw UV image editor spaces

This is in order to use batch cache directly without using tricks like
batch presets reseting the VAOs.

Note: For now it also create a depth buffer for this area which is not
needed. We could get rid of this to lower VRAM usage.

BMesh: Add BM_face_calc_area_uv

Texture Paint: Add filtering option for texture paint overlay

The overlay should now use the texture interpolation setting in material
mode.

In image mode, there is now a new button to let the user choose the texture
filter. The option is located in the Texture Slots popover and only shows
in Image mode.

Workbench: Support node texture "closest" interpolation option

This makes it possible to paint pixel art using the workbench.

Cubic interpolation is not supported but could be added if needed.

GPUShader: Cleanup Unused shaders

Mesh Batch Cache: Cleanup Unused

Edit Mode Selection: Make Vertices not occluded by edges

Debugging the edit mode selection I realized the vertices are often
occluded by edges with the same depth. Sometime it can be the center
pixel of a vertex point and that can lead to some selection issue.

So I increased the offset a bit for the vertices and it seems to fix it.

GPUMaterial: Cleanup / optimization

Mesh Selection: Port to batch cache request

This makes it more future proof and remove baked id offset inside the vbos.
Instead we add the offset as a uniform. This makes it possible to reuse
the vbos instead of discarding them all the time.

Also using batch request may reduce batches creation time.

Mesh Batch Cache: Fix wrong assert

GPUShader: Add selection id shader

This is to separate id drawing from standard color drawing.

Mesh Batch Cache: Put context evaluation out of batch cache

This is in order to be able to call DRW_mesh_batch_cache_create_requested
outside of the draw manager

DRW: Fix texture paint crashing if object has no material slot

Merge branch 'blender2.7'

Fix T60227: Crash when Cycles uses more than system threads

Tweaked scheduling so it survives this situation by scattering
"extra" threads uniformly over all the NUMA nodes.

There are still tweaks possible to make some specific hardware
configurations work better.

pull animated bind update calls out of loop

the function does a loop on its own (over meshislands in fm)

Cycles: Disabled anisotropic texture cache lookups for emission shaders.

Leaving it enabled lead to excessive render times in certain scenes.
