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.

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The viewport_quality setting has been replaced by the viewport_aa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.

Workbench/Eevee now displays multiple multi-materials correctly.
Iterate over pbvh nodes when doing object iteration. This makes the
rendering process more streamlined and allow for using different materials.
This change will make possible to:
- Add culling pass of each pbvh leaf node. (speedup if zoomed on a small
area)
- Reduce number of lead node iteration.
- Reduce code complexity
- Add `render_aa` and `viewport_aa` sampling setting for workbench. 0
samples means no AA, 1 sample uses FXAA and more samples will use
TAA.
The viewport `gpu_viewport_quality` can still limit viewport anti-aliasing
method.
- Use TAA when rendering images. (this used to be CPU based FSAA)
- Removed `R_OSA` related settings.

Currently it is not possible to view the vertex colors of an object. To
optimize the workflow, workbench will need to support Vertex Colors.
The Vertex Colors is a new option in `shading->color_type`. When objects
do not have vertex color, the objects will be rendered with the
`V3D_SHADING_OBJECT_COLOR`.
In order to support vertex colors in workbench the current texture/solid
shading structure is migrated to a primary shaders and fallback shaders.

Edit mode shows the mesh elements in X-ray mode even if alpha is set to
1. Now the code takes this into account so that you can still select
visible mesh elements in X-ray edit mode.
view3d_draw_legacy need to be updated with the new XRAY flag macros to
avoid crashes. Additional cleanup of the XRAY macro flags were done.
Now the depth order of objects when trying to select them is only used when not in X-ray mode.
Before, this was only the case in wireframe mode regardless of X-ray settings.
I've also unified the usage of V3D_XRAY and XRAY_FLAG as they were basically copies of each other.

When texture drawing was enabled the fallback materials were not transparent.
The reason was that the solid material was requested. This patch will requesting

When texure shading is enabled, the transparency accum shaders were not set/updated.
This resulted into a crash when transparent objects were rendered when shading mode

Due to recent changes the AA was not rendered in the viewport when not
interacting. When interacting it was. This was due to incorrect
detemination to perform TAA.
When Specular Transparent materials are used the world clipping
did not work on the transparent materials. The reason was that the
accum shaders did not vary on the existance of the clipping planes
This patch will variate the accum shaders when clipping planes are
active.

Workbench render engine did not work when an odd number of AA samples
were used. A user could enter these values by disabling AA or set the
number of AA samples in the Render/Film panel to an odd number.
This commit will not perform TAA passes when AA is disabled.
For supporting the setting of 5 or 11 samples the bitmask was replaced
by an if statement as this was making the odd number not render
correctly.
As extra introduce the jitter samples of 5 and 11 so the images will
be more clean. a jitter sample of 11 used to read outside the allocated
space of the jitter samples.

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.
As discussed with @billreynish this makes little sense now that we don't
have a dedicated textured mode. We don't have a superior texture or shaded
mode anymore and we also cannot mix different engines together (workbench
with eevee/lookdev).
The only feature it removes is the possibility to hide textures for certain
object in solid mode.
