GPUFrameBuffers were being free when no context was attached or in the
wrong gl context. This make sure this does not happen again.
You can now safely free any gl resource from any thread (well as long as
it's not used anymore!).
This does not include all the struct and type renaming. Only files were
renamed.
gwn_batch.c/h was fusioned with GPU_batch.c/h
gwn_immediate.c/h was fusioned with GPU_immediate.c/h
gwn_imm_util.c/h was fusioned with GPU_immediate_util.c/h
This does not fix the smokesim. It only port the drawing method.
The Object mode engine is in charge of rendering the velocity debugging.
Things left to do:
- Flame rendering.
- Color Ramp coloring of volume data.
- View facing slicing (for now it's only doing sampling starting from the
volume bounds which gives a squarish look)
- Add option to enable dithering (currently on by default.
Features to get the 2nd, 3rd, 4th closest point instead of the closest, and
various distance metrics. No viewport/Eevee support yet.

This works for Cycles, Eevee, texture nodes and compositing. It helps to
reduce the number of math nodes required in various node setups.

- Texture creation now requires explicit data type.
- GPU_texture_add_mipmap enable explicit mipmap upload.
- GPU_texture_get_mipmap_size can be used to get the size of a mipmap level
of an existing GPUTexture
- GPU_texture_read let you read back data from a gpu texture.

Original description:
I've encounterd into a problem with blender 2.8.
See the example screenshot (scene, shader setup). For some materials it's not enough to calculate hash based on fragment code and defines. In some cases attribute names may change. And if we change uv set name, for example, vertex shader is not recompiled, and another attribute name inside it is used.
This has wrappers for the most common gl* functions in the codebase, and is in preparation for D3502

We have to discard the batch in smooth case, because we are modifying
the index buffer (flat shading don't need it, only changes vertex buffer
on redraw, which is safe).
Many thanks to @fclem for his help on debuging/understanding what was
wrong here!
In an effort to centralize all opengl calls in the codebase, this patch replaces
the raw opengl calls in bf_blenfont with GPUTexture so it's no longer depended
on opengl headers.

Differential Revision: https://developer.blender.org/D3483
this is to highlight areas in the code that still directly do opengl calls or use
opengl types.
This is in preparation for supporting alternative rendering back-ends.

This means the shader can now be used for procedural texturing. New
settings on the node are Samples, Inside, Local Only and Distance.
