This moves the flash on mode transfer effect option from the overlays to
an operator property of the mode transfer operator.
- This effect is intended to show the target object when no overlays or
a minimal set of overlays is enabled. Making it part of the whole set of
overlays invalidates this use case.
- The effect is not intended to be configurable per viewport, it should
be a global option.
The effect is still implemented using the overlay engine (instead of a
draw modal callback) due to performance and drawing artifacts. Having it
implemented as an overlay with runtime timer data in the objects makes
also possible to run multiple animations at the same time without any
visual glitches.

This overlay renders a flash animation on the target object when
transfering the mode to it using the mode transfer operator.
This provides visual feedback when switching between objects without
extra overlays that affect the general color and lighting in the scene.
Differences with the design task:
- This uses just a fade out animation instead of a fade in/out animation.
The code is ready for fade in/out, but as the rest of the overlays
(face sets, masks...) change instantly without animation, having a fade
in/out effect gives the impression that the object flashes twice (once
for the face sets, twice for the peak alpha of the flash animation).
- The rendering uses a flat color without fresnel for now, but this can
be improved in the future to make it look more like the shader in the
prototype.
- Not enabled by default (can be enabled in the overlays panel), maybe
the defaults can change for 3.0 to disable fade inactive and enable this
instead.

This was caused by the paint overlay drawing after the infront pass.
Moving the paint overlay before it fixes the issue. We might even do
that for more mode overlays.
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.
Stores cryptomatte hashes as meta data to the render result. Compositors could
use this for lookup on names in stead of hashes.

This change will use the image engine to draw the backdrop of the compositor. With this patch the alpha blending will be done in Linear Scene Reference space and shows pure emissive colors.
See differential for an example image.
**Technical changes**
As only the backdrop drawing is done using the draw manager there are some technical changes.
1. The overlay buffer is partly drawn outside the draw manager. When drawing the backdrop image the overlay buffer needs to be masked to simulate premultiplied alpha under.
2. The backdrop of the node editor is done in region pixel space. A `DRWView` is constructed with this space.
3. UDIM textures uses world position to generate the UV coordinates. This has been implemented more strict by the `IMAGE_DRAW_FLAG_USE_WORLD_POS`. When the flag isn't used the local coordinates are used to generate the UV coordinates what is image space.
4. The draw manager now checks the actual `eSpaceType` of the space data to use different code paths. In the future the movie clip editor will be added.
NOTE: The preview images in nodes are drawn in display space and cannot show pure emissive colors. As preview images are used on more locations it is best to fix this in a separate patch.

The volumes are not a line type and should not be render into the line

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

* 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.

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.

This patch also optimize the case when pointcloud has uniform radius.
However we should premultiply the radius prop by the default radius
beforehand to avoid a multiplication on CPU.
Using geometry instead of pseudo raytraced spheres is more scalable as
we can render as low as 1 or 2 triangle to a full half sphere and can
integrate easily in the render pipeline using a low amount of code.

The reason whas that the painting overlay wasn't initialized in the
first sample, but the draw passes and groups were filled. Resulting in
rendering the overlay twice or not at all.
This change moves the assignment to where it is valid.
Due to legacy this overlay was implemented twice (Edit Mesh and Weight
Painting) with different results. This patch consolidates both drawing

This method gives really nice results but has some downside:
- Require a depth copy or loose the ability to write wire depth to the
depth buffer and have correct depth ordering of wires. This patch use the former, with its associated cost.
- Require some depth sampling and prevent early depth test (i.e: has
some performance impact).
- Has some relatively minor instability with geometry that are perpendicular
to the view and intersecting with other geometry.
Pros:
- Compared to a fullpass approach this is surely going to have less
performance impact and much higher quality.
- Removes the additional vertex offset. (see T74961)
- Fixes all half edges z-fighting.

When using duplicate linked meshes, objects that are not in edit-mode will be drawn as
it is in edit mode, when another object with the same mesh is in edit mode.
This will not be the case when one of the objects are influenced by modifiers. The change
reflects more how it was done in Blender 2.79.
The current change introduces a draw manager method that checks in detail who is responsible
for the drawing (render engine or overlay engine). If the edit mesh is not the original or
the object that is drawn doesn't draw the original mesh the object will be drawn by the render
engine.
Known Limitation of this patch is that the rendering outside edit mode doesn't reflect the
latest changes until the user switches between object and edit mode. When there are no
modifiers in use, the updating is done immediately.
IMO this would be sufficient for blender 2.82, it also fixes parts of T72733.
The updating of the surface batches requires more development and is
post-poned for now.
