Draw manager was checking for particles being enabled in viewport, but
actual evaluation was happening for render. Now the check in draw manager
properly follows current evaluation mode.
Additionally, de-duplicated some check, by moving everything needed to
a single place.
Annoying part is the const-cast, that could be cleaned up later by
modifying some underlying functions.
Needed to fix T61196, supporting clipped back-buffer in the 3D view
which is done outside the draw module.
It was also inconvenient having DRW_shader_* versions of GPU_shader_*
API calls.
- Clipping distances are now supported as a shader configuration
for builtin shaders.
- Add shader config argument when accessing builtin shaders.
- Move GPU_shader_create_from_arrays() from DRW to GPU.
BF-admins agree to remove header information that isn't useful,
to reduce noise.

Developers should add non license comments as separate comment blocks.
No need for separator text.

This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.
See P901 for script to perform these edits.
This now only upload data per loops to the GPU, making use of index buffer
to draw polygon. This make use of the vertex cache, speed up renders
and saves a lot of vram.
Update performance is also slightly faster and can even be improved further
by updating only uvs or vcol independently.
This commits breaks texture paint batches. It will be added back in another
commit.
For simplicity we choose to execute the rendering of Opengl engines in the main thread and block the interface.
This might be addressed in the future at least for video rendering.
A drawmanager wrapper (DRW_render_to_image) is called by the render pipeline to set up the Opengl state and then call the specific draw_engine->render_to_image function.
This replaces dedicated flag which wasn't clean who sets it and who clears it,
and which was also trying to re-implement existing functionality in a way.
Flushing is not currently very efficient but there are ways to speed this up
a lot, but needs more investigation.

From GL spec :
GL_INVALID_OPERATION is generated if mask contains GL_DEPTH_BUFFER_BIT or GL_STENCIL_BUFFER_BIT and the source and destination depth and stencil formats do not match.
So blitting framebuffer with depth or stencil require the SAME FORMAT.
-Use 11_11_10 buffers for hdr content.
-Eevee compositing share 1 buffer if bloom and DOF are both activated.
-Fix slowdown when resizing EEVEE viewport.
-Removed DRW_BUF_*** enums causing confusion.
This add a new set of (possible) render settings that can be defined at
the scene level and overridable at the scene layer level.
Once we get workspaces we can either add workspace inbetween scene and
scene layer evaluation. Or to replace layer settings, to avoid extra
confusion to users.
An example of this setting is "samples", as implemented now for the clay
engine.
