Cycles: added ray differentials to henyey-greenstein phase function

Cycles: Moved texture coordinate differential creation to after all bump maps are created. This should improve texture caching in scenes with bump/displacement maps.

Cycles: Fixes for texture caching, behavior with auto convert off was broken, color space was misinterpreted sometimes.
Note: Texturing with OSL is currently broken.

Cycles: Smaller fixes for differentials, taking dNdu inot account when getting N from a bump shader

Ccyles: texture differentials now respect the hidden mapping node inside the image texture node.

Cycles: fix for mip map paths

Cycles: Changed Mip Map names to replace, not add to suffix
Added oiio_make_tx() call to Cycles' Python API

Cycles: improved ray differentials for specular/glossy closures with DNDU/V enabled

Cycles: more accurate differential approximation for glossy bounces

Cycles: Don?t apply glossy blur texture filtering on singular paths

Cycles: fixed normal differentials, ShaderData now contains dNdx/y instead of dNdu/v

Workbench: Added a quality slider for the viewport

Currently only attached to the Anti Aliasing of the solid mode of the
viewport. But eventually we could add other options here. Quality
setting can be found in the System tab of the userpref.

The slider goes from No Antialiasing (0.0 - 0.1) to FXAA (0.1 - 0.25) to
TAA8 (0.25 - 0.6) to TAA16 (0.6 - 0.8) to TAA32 (0.8 - 1.0)

Cycles: added diffuse_blur and glossy_blur parameters to texture cache

Theme: Further polishing and unifying on Flatty Dark Blueberry

With feedback from @campbellbarton for better contrast in edit mode.

Cycles: Smaller updates to texture cache, setting a few more options and letting textureSys do the flipping instead of doing it manually

Cycles: fixed include statements for image cache to work on case-sensitive file systems

Cleanup: Rename File

Cycles: added blurrier texture lookups for indirect diffuse paths

Cycles: Added dPdu/dPdv to area ligths so we can use filtered textures on them
