Camera background images were not shown under transparent objects.
This patch performs an alpha under for background images for cycles.
In order to see the difference the Film transparency needs to be turned on.
Note that workbench and EEVEE still needs to be adapted as they don't
write store alpha value in the viewport.
Side note. This implementation is already an improvement of the current behavior, what users are requesting. (Show background images underneath cycles viewport rendering.) It is clear that this patch still needs to be extended to workbench and eevee. For now that should be marked as a known limitation.

BF-admins agree to remove header information that isn't useful,
to reduce noise.
- BEGIN/END license blocks
Developers should add non license comments as separate comment blocks.
No need for separator text.
- Contributors
This is often invalid, outdated or misleading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.
TH_BACK was being used when drawing the 3D view even though
there was no way to set the color in the preferences.
The color was zero'd when moving to the new 2.8x theme.
Having both gradient and background colors was confusing,
especially having to use 'TH_HIGH_GRAD' for the 3D view, 'TH_BACK' for
other views.
Move the background color back to 'TH_BACK', 'TH_BACK_GRAD' is used
when gradients are enabled.
RNA is unchanged so presets don't need updating.
Now it shows more compact info below the view/object name. Render time and
memory usage is left out, as in most cases this is not so important. These
could be added back optionally if needed.
Avoid accessing object mode via the view layer active object
when drawing since it's done everywhere we store the active object mode
in the draw-context.
Replaced the draw world option with a shading.background_type enum.
Where the user can select Theme, World or a Custom color.
World and theme colors do not always work in workbench. We needed to
have an option what the user could control locally (per viewport).
Especially when using linked data.
I removed the world background drawing from the draw_manager. It was never used as EEVEE and Workbench both override the logic.
Not 100% sure about the naming of Theme, World, Viewport.
In other parts of blender's codebase World is sometimes called Scene.
Will stick to the names that describes its location best.

This is because depth test is set before drawing anything now. There is no
case where we want to draw without depth test that is not selection and
this case is not handle by v3d->zbuf anymore.
UI assume depth test is off by default. The DRWManager assume it's on.
This should fix T55623.
Dithering the output color for 8bit precision framebuffer with bayer matrix.
On my tests the bayer matrux patterns are not noticeable at all.
Note that it also does that in opengl rendered mode which can be in a much
higher bitdepth. We can fix that if that's a problem in the future but I
doubt it will.
