This removes code duplication and put an end to the old "create at request"
batch creation.
Also it uses the same vbo as the uv layer used for shading. Reducing VRAM
usage.
Also fixes the modified uv display in uv edit mode.
This is in order to allow more spaces to have their batches created at the
same time and sharing the batches.
This is part of the effort fo making the drawing code more optimized. This
commit however should not introduce any difference.
This commit bypass the aspect ratio correction for angle stretch display
but this should be fixed in the next commit.
This is in order to use batch cache directly without using tricks like
batch presets reseting the VAOs.
Note: For now it also create a depth buffer for this area which is not
needed. We could get rid of this to lower VRAM usage.
The overlay should now use the texture interpolation setting in material
mode.
In image mode, there is now a new button to let the user choose the texture
filter. The option is located in the Texture Slots popover and only shows
in Image mode.
Debugging the edit mode selection I realized the vertices are often
occluded by edges with the same depth. Sometime it can be the center
pixel of a vertex point and that can lead to some selection issue.
So I increased the offset a bit for the vertices and it seems to fix it.
This makes it more future proof and remove baked id offset inside the vbos.
Instead we add the offset as a uniform. This makes it possible to reuse
the vbos instead of discarding them all the time.
Also using batch request may reduce batches creation time.
Tweaked scheduling so it survives this situation by scattering
"extra" threads uniformly over all the NUMA nodes.
There are still tweaks possible to make some specific hardware
configurations work better.
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.
This was only used by collada export metadata.
If metadata like this is needed, we can use per-filetype preferences,
to make it clear when user identifiable information is being used.
We should *never* prevent copying basic mesh CDLayers (vertices etc.),
that does not make sense.
I guess issue was not in old DM because geometry was duplicated anyway,
and in 'normal' modifier stack eval, probably because bare mesh was
awlays requested? But we should not have to be explicit here about it.
This is a part of another which, which needs to tag owner
of f-curve for an update. But since this is too many lines
changed committing separately.
Basically, for f-curve AnimElement we are now storing ID
whih owns the f-curve.
When holding down the key for a while, the pie menu will disappear when
releasing the key. This is under the assumption that in this case the user
decided to cancel the action.

There was a problem in the caps start and in some situations, the pixel was wrong.
Also changed the way the caps are detected because use the alpha in negative was a hack that maybe will not work with all drivers.
