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.

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.

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
Enabling the drawing of the mesh analysis overlay.
Currently the settings are part of the scene toolsettings. What makes sense,
for 3d printing, but does not fit well with the per viewport blender 2.80
overlays.

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.

This improve visibility in edit face select mode by using the face select color
instead of the edge select color (which is in default theme a bit more red). Also
makes the selected edges in this mode a bit more opaque (0.75 instead of 0.4).
Full opacity is still reserved for edge select mode.
The `AMD Radeon HD 7600M` compiler is usually buggy for Geometry Shaders.
In this case, indexing was causing problems in `gl_in[i].gl_ClipDistance[0]`.

When in Axis alligned orthographic view a grid was always displayed.
With this change the user can enable/disable this grid.
The Grid is always visible and editable, but only rendered active when user is in quad view, or axis aligned ortho view.

This removes the large edges and instead use colors to hint in which
selection mode the user is.
The component in each individual selection mode is more prominent to add
more emphasis. The other components are less prominent and dimmed.
A minor default theme changes needed to be made to keep clarity in all
combinations.
Forcing old behavior (no selection mode hit) could be done quite easily
by just making the 2 booleans true (selectFaces and selectEdges).

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.

The issue was the manipulated depth for images would be used when doing distance depth checks.
Now we will use the actual depth of the image object when doing such tests.
