Clamp uvs when not drawing repeat image

Enabled framebuffer assert

Added comment to `do_populate_loop`

Renamed `image_gpu_texture_update` to `image_gpu_texture_get`

Enabled workaround to solve threading issues in draw manager

This workaround addresses T79533 and T79038 for Blender 2.90. The
solution isn't clear and needs more research and work. In order to
continue with blender 2.90 release it was proposed to add this work
around.

It has been tested with the test files provided in the reports.

Cleanup: use doxy sections

Fix T80077: Objects disappear when joining with a zero scaled axis

Use invert_m4_m4_safe_ortho when joining objects so zero scaled axis
doesn't cause all points to be scaled to zero.

Instead geometry is left un-scaled on degenerate axes.

Report a warning in this case since users may want to adjust the
active objects scale.

BLI_math_matrix: add invert_m4_m4_safe_ortho (m3 version too)

Unlike invert_m4_m4_safe, this calculates zeroed axes.
Useful when we need to use the inverse of an objects matrix,
keeping the valid axis, only filling in the zeroed ones.

fixed ctrl-z bug

Some (partial dummy) additions to the Asset Browser UI

* Add search button
* Add filter and display options popups from the File Browser. These might have
to be tweaked for the Asset Browser, but adding the buttons as a first step
to fill the space.
* Add properties sidebar toggle button (gear icon, like in the File Browser)
* Add dummy repository selector
* Use placeholder icon for Asset Browser editor

Add list of asset categories to the left sidebar

The categories are the same you can find in the File Browser filter popup:
Scenes, animations, object & collections, geometry, shading, images & sounds,
environments and miscellaneous.

And again, all of this is more of a prototype, things will change a lot still.

By default, show object assets in $HOME/assets.blend

Obviously using this fixed path is a temporary hack. Right now goal is really
just to get quick visual results to test and evaluate.

no self collision if obstacle collision

Sculpt: Cloth Snake Hook Brush

This implements Snake Hook as a deform type for the cloth brush. This
brush changes the strength of the deformation constraints per brush step
to avoid affecting the results of the simulation as much as possible. It
allows to grab the cloth without producing any artifacts in the surface
and create more natural looking folds than any of the other deformation
modes.

Fix T80008: Smooth brush not deforming mesh boundaries correctly

In 2.83 and previous versions there was a bug that was causing boundary
vertices to be detected incorrectly that was preventing the smooth brush
to work on boundaries if there was a pole on them.
In 2.90 the boundary vertex detection was fixed, but it was still using a
simplified version of the algorithm without any boundary smoothing. This
patch implements a similar smoothing algorithm to what I think it was
the intention of 2.83 and previous versions, but working correctly.

Cleanup: Rename SpaceFile.mode to SpaceFile.browse_mode

This differentiates between regular file browsing and asset browsing.
