overlay_edit_uv_cache_populate as well.

A fix for T83187 (rBf83aa830) assumed in the overlay code of the uv editor that the object was a mesh
when it did not have to be - causing a crash.
The fix makes sure that the object is a mesh.

Caused by rBf83aa830cd00.
Since above commit, only meshes in editmode were considered for drawing
(because
BKE_view_layer_array_from_objects_in_edit_mode_unique_data_with_uvs was
used), but the option needs to work for texture paint mode as well, so
use BKE_view_layer_array_from_objects_in_mode_unique_data instead on
pass the draw_ctx->object_mode.
note: there is no good filter_fn to check if we have UVs if mesh is not
in editmode, this shouldnt cause much of a performance hit though.

When uv editing objects that share the same mesh only the selection
state can get confused. The cause is that the UV editor uses a
particular order of objects and store its state in the first object of a
mesh it hasn't handled. During drawing this state is updated into the
GPU buffers. In the case of linked meshes it can happen that the GPU
buffers are updated based on the object that does not have the correct
selection state making th selection VBOs incorrect.
This patch adds a work around that uses the order that the UV editor is
also using so the GPU buffers are built with the right data.
The mask overlay wasn't part of the overlay engine. The reasoning nehind
this was that more editors used the mask overlay and most of them used
old drawing code. This patch adds the mask overlay drawing to the draw
overlay engine. This code path will only be used by the image editor
VSE, Compositor and Movie Clip editor will still use the previous
method.
During this patch some alternatives have been researched:
1. `ED_mask_draw_region`: this would lead to different code paths when
drawing in the image editor, and some hacks to retrieve the correct
framebuffer.
2. Add mask drawing to image engine: Would lead to incorrect color
management when viewing the mask.
3. Add mask drawing to image engine and overlay engine: Would lead to
duplicated code.
4. Add mask drawing to overlay engine and for combined overlay select
the correct framebuffer.
Option 4 was chosen as the exception (switching framebuffers) can be
done without hacks. The code stays clean.
Active tile could be NULL when it was on the second tile before
switching back and forth between the Image/UDIM.
In the future we might also check that the active_tile_index is always
valid.
The clone tool in the image editor can show a second texture on top
of the image. This wasn't ported and now results into alpha and depth
issues. This fix adds the clone tool drawing to the overlay engine.

The overlay options in the image/uv editor is hidden in side panels and menus. Sometimes this panel is even hidden, while still useful.
The goal of this task is to introduce an overlay pop-over just like the overlay-popover of the 3d viewport.
Popover has
* UV Stretching (only available in the UV mode, when active object mode is a mesh and in OB_EDIT mode)
* Display As (only available in the UV mode, when active object mode is a mesh and in OB_EDIT mode)
* Show Modified (only available in the UV mode, when active object mode is a mesh and in OB_EDIT mode)
* Show UV Edges (including opacity slider; available UV, View, Paint, when active object mode is a mesh and in OB_EDIT mode)
* Udim tiles when no image is available.
Like the 3d viewport, there will be a editor toggle to enable/disable the overlays
For compatibility reasons the RNA properties are added to both the `SpaceImage.uv_editor` amd `SpaceImage.overlay`. On DNA level they are still stored in the SpaceImage. only new properties are added to the SpaceImageOverlay struct. During the next major release we could remove these options from `SpaceImage.uv_editor`. This should be noted in the Python section of release notes.

The old image editor has an option to enable the smooth wire drawing.
This option was stored per editor and disabled by default. This patch
connects the smooth wires in the UV/Image editor to `User Prefereces ->
Viewport -> Quality -> Smooth Wire [] Overlay`.
The old option is left in place and will be removed when the old image
editor drawing code will be removed before BCon 3.
This project moves the current UV/Image editor drawing to the draw manager.
Why would we do this:
**Performance**:
Current implementation would draw each texel per time. Multiple texels could be
drawn per pixel what would overwrite the previous result. You can notice this
when working with large textures. Repeat image drawing made this visible by
drawing for a small period of time and stop drawing the rest. Now the rendering
is fast and all repeated images are drawn.
**Alpha drawing**:
Current implementation would draw directly in display space. Giving incorrect
results when displaying alpha transparent images.
This addresses {T52680}, {T74709}, {T79518}
The image editor now can show emission only colors. See {D8234} for
examples.
**Current Limitations**
Using images that are larger than supported by your GPU are resized (eg larger
than 16000x16000 are resized to 8k). This leaves some blurring artifacts. It is
a low priority to add support back of displaying individual pixels of huge
images. There is a design task {T80113} with more detail.
**Implementation overview**
Introduced an Image Engine in the draw module. this engine is responsible for
drawing the texture in the main area of the UV/Image editor. The overlay engine
has a edit_uv overlay which is responsible to draw the UV's, shadows and
overlays specifically for the UV Image editor. The background + checker pattern
is drawn by the overlay_background.
The patch will allow us to share overlays between the 3d viewport and UV/Image
editor more easily. In most cases we just need to switch the `pos` with the `u`
attribute in the vertex shader.
The project can be activated in the user preferences as experimental features.
In a later commit this will be reversed.
