- Disable VertexPaint and WeightPaint for OB_MATERIAL and OB_RENDER. Users want to see the final result
- When in OB_SOLID, the active object should be rendered without any color. The lighting information is multiplied with the VertexPaint/WeightPaint color
- Removed the use_shading flag from VertexPaint and WeightPaint
- add method to check if render engine should draw without color (DRW_object_in_only_lighting_mode)

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 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.
Same as MEM_SAFE_FREE macro,
checks for NULL, runs free then sets NULL.
Blocks of code that do this many times are noisy and likely
errors here wouldn't be noticed immediately.
Also NULL's static vars which were being left set.
This removes MAX_STORAGE, MAX_BUFFERS, MAX_TEXTURES, MAX_PASSES limits.
Actual memory saving isn't so important, it just means we don't need to
manually bump these based on changes to engines.
