The previous commit disable the fast drawing if the background texture was not ready, but it did not detect the Painting mode, so the fast was always disabled.
Now the check is done inside paint mode.
There were some problems in the engine because the data was saved inside e_data struct, but this struct is reset sometimes and the background texture is not valid.
Now, the data has been moved to stl->g_data and all creation and free has been moved to use stl->g_data. This fix also some small memory leak for the Buffer GPUBatch data.
The background texture has been moved to texture list because must be available all the time. When is not drawing, the texture is removed to safe memory. Also, if the mode is painting and the texture is not ready because it was removed by Draw Manager, the texture is reloaded with the background image again. This ensure the background image is always visible when painting.
Also I have used this patch to reduce the size of texture used for background to 16F instead of 32F and the blank texture to 1x1 pixels instead of 16x16.

This reverts commit 36faf739a7.
Somewhat annoying but this change had some unforeseen consequences,
which lead to an actual bug.
Since this change was not sufficient to get original report fixed
is easier to simply revert for now.
Fixes T65842: Hair disappears when clicking on particle system name
Migrate old legacy code to the draw mamager/object mode. The old legacy
version did not work with wireframe. By migrating the code
to modern draw manager code we have mode control on the drawing process.
Still background images do not work with OIT, the cause seems to be that the transparent pixels are treated as background pixels.
Also There are some artifacts when working with Holdouts and DoF, this
is because the draw engines do not pass the correct alpha values.

The Pose Bone Selection used normal matric multiplication, but that
mismatched the Depth buffer from all draw engines. They used the
optimized matrices from common_view_lib.
This change will use the optimized version, so the depth buffer matches
and the render artifacts would be correct.
Please note that bone selection is not using shcfg and therefore render clipping is still off.

When performing F12 render on a transparent film all solid objects where
a bit transparent. Single Pass AA and no AA passes were not visible at
all.
Issue was that the first frame was not handled correctly making these
artifacts. This commit changes the order of `GPU_state_init` and
`DRW_state_reset` so the state is correct during the first pass.
This changes behavior from 2.7x, where selection & cursor could be
occluded by other objects.
Doing this without z-fighting in 2.8x isn't so simple because drawing
the text geometry is separated from edit-selection.
Change behavior since this doesn't seem like an important difference.
Fixes assert drawing text edit mode.
- was using wrong offset [index instead of index * 4]
- also minor correction to variable naming

This was because the VAOs were not updated if an instance batch was
reusing a VBO containing instances attributes which was reinitialized.
Now we ensure the Batch will reconfigure the VAOs if the VBO is 0.
Allows it to be preserved during copy-on-write update when on-geometry
related update is needed.
This is a required part for T63537, where we need to preserve the entire
evaluation data when object is tagged for only RECALC_COPY_ON_WRITE.

Cheap tip: anything that is not "Camel Case" and/or that is more than
a few words long should use `TIP_` translation, not `IFACE_` one.
Also added several missing strings (including the one reported in D5056
by Jean First (@robbott), thanks).
This was due to a double offset of the wireframe. We also reduce
the wireframe offset. The look of the wireframe overlay changes
a little with on distant wires.
Now texture storage of images is defined by the alpha mode of the image. The
downside of this is that there can be artifacts near alpha edges where pixels
with zero alpha bleed in. It also adds more code complexity since image textures
are no longer all stored the same way.
This changes allows us to keep using sRGB texture formats, which have edge
darkening when stored with premultiplied alpha. Game engines seems to generally
do the same thing, and we want to be compatible with them.
The OpenGL state was not set to blender defaults when using
`DRW_render_to_image` path. This is only used when doing F12-rendering.
Cause of changes with the `RESTART_INDEX` hair rendering was rendering
the restart_index as an actual vertex index.
