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.
