Merge from trunk r47744-r48564

Enable velocity drawing temporarely

Smoke Vorticity/turbulence: Porting the code idea from new turbulence paper. Moving obstacles will generate turbulence/vorticity now. This allows for a very natural reaction of smoke to obstacles.

Part of my Blender Smoke Development Phase III.

Cleanup, move 2D paint stuff to their own file.

Some temporarily changes for GLES.
Plus attrib location assigning for GLES.

Armature Importer fix.
Bone length and tail values.

Adding GPU object:
Handles Vertex and Normal drawings as they are different between ES and desktop version.
In future, it should handle color, textures, maybe effects.


How it does it:
Desktop version:
* Calls usual gl functions for doing these things. For example glVertexPointer
ES version:
* Gets location of corresponding attributes at shader creation.
* Also stores matrixes' locations
* Before drawing, we select corresponding storage to the shader/object
* When we call functions, we set attribute to given pointer at recorded location

We need "extern" to use GPU_functions outside of gpu module because they are actually variables.

Fixes for brush size and overlay in image editor

merge with trunk 48524

ArmatureImporter.cpp refactor.

bridge initial commit

Convert Fonts to software matrix stack.

Adds software image scalling. Supports scalling between 0.5 and 1.
Temporally changed minmap generation. GPU Minmap is only for ES devices for now.
Added definitions for GLES shader generation.

Fixes gpu_functions.c for OpenGL ES

Export Armature fix.
Instead of exporting pose_mat, exporting arm_mat now.

- Add CG helper for difficult setups
- Remove unsued code

Remove old files from old Eigen version

Update Eigen to latest git version

WIP comit: put preconditioners in a seperate function, use a loop macro
