This is in order to have VAO handled by thoses batches instead of using a
common VAO. Even if the VAO has no importance in these case using a batch
will help when transitioning to Vulkan.
Cycles lights now use strength and color properties of the light outside
of the shading nodes, just like Eevee. The shading nodes then act as a
multiplier on this, and become optional unless textures, fallof or other
effects are desired.
Backwards compatibility is not exact, as we can't be sure which renderer
the .blend was designed for or even if it was designed for a single one.
If the render engine in the active scene is set to Cycles, lights are
converted to ensure overall light strength remains the same, and removing
unnecessary shader node setups that only included a single emission node.
If the engine is set to Eevee, we increase strength to remove the automatic
100x multiplier that was there to match Cycles.

Cycles now uses the color space on the image datablock, and uses OpenColorIO
to convert to scene linear as needed. Byte images do not take extra memory,
they are compressed in scene linear + sRGB transfer function which in common
cases is a no-op.
Eevee and workbench were changed to work similar. Float images are stored as
scene linear. Byte images are compressed as scene linear + sRGB and stored in
a GL_SRGB8_ALPHA8 texture. From the GLSL shader side this means they are read
as scene linear, simplifying the code and taking advantage of hardware support.
Further, OpenGL image textures are now all stored with premultiplied alpha.
Eevee texture sampling looks a little different now because interpolation
happens premultiplied and in scene linear space.
Overlays and grease pencil work in sRGB space so those now have an extra
conversion to sRGB after reading from image textures. This is not particularly
elegant but as long as engines use different conventions, one or the other
needs to do conversion.
This change breaks compatibility for cases where multiple image texture nodes
were using the same image with different color space node settings. However it
gives more predictable behavior for baking and texture painting if save, load
and image editing operations have a single color space to handle.

By default the texture is locked and only the box is aligned when Follow Drawing Path is enabled.
Before, when the Follow was disabled, the texture was always aligned to top and it was not affected by object rotation. Now, the texture always is rotated with object rotation.
The DrawManager assumed that the first render layer was the render layer
where GP needed to render on. In viewport this is always the case as we
only have a single view layer. When rendering this can be multiple when
multiple layers are rendered and composited in the compositor.
In stead of the assumption that the first render layer is the render
layer we need to draw on, we search for the render layer with the same
name as the viewlayer.

In recent changes the viewport_quality setting was not working what
users expected. This change will separate the anti-aliasing method that
is being used.
We now have three settings:
* scene.display.render_aa: Will be used during `Render Image`.
* scene.display.viewport_aa: Will be used during `Viewport Render Image`.
* userpref.viewport_aa: Will be used in the 3d view.
The viewport_quality setting has been replaced by the viewport_aa
setting as it was the only thing in currently controlled.

When using multiple viewlayers and switching between them the selection
gets buggy. The reason for this is that the select_id is updated based
on the index in the viewlayer. This makes the select_id not unique as
objects might be shared or not shared at all.
This fix will update the select_id on all objects in main. This will be triggered in all the selection operators.

This change the logic a bit, when 2 bsdfs using SSS are mixed, we use the
one with the biggest radius (on a per pixel basis).
This change from previous behavior which was to select input 1 if radius
was greater than 0.
