Now the behaviors are consistent for blend, image and text files:
- If the file is not writable, will report it.
- If the file is new (without a path), save as will be used.
- If the file was deleted, will try to recreate it.
Ref D6755
With D8234 a new drawing method for UV/Image editor was introduced. For debugging
reasons we left the old drawing method in the code base. This patch will remove
the old drawing method.

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.

Define enum `eContextResult` and use its values for returns, instead of
just returning 1, 0, or -1 (and always having some comment that explains
what -1 means).
This also cleans up the mixup between returning `0` and `false`, and `1`
and `true`. An inconsistency was discovered during this cleanup, and
marked with `TODO(sybren)`. It's not fixed here, as it would consititute
a functional change.
The enum isn't used everywhere, as enums in C and C++ can have different
storage sizes. To prevent issues, callback functions are still declared
as returning`int`. To at least make things easier to understand for
humans, I marked those with `int /*eContextResult*/`.
This is a followup of D9090, and is intended to unify how context
callbacks return values. This will make it easier to extend the approach
in D9090 to those functions.
No functional changes.

When Showing Meta data for an image where the buffer does not exist
(missing file) it crashed. This patch removes the check on the image and
only checks the availability of the buffer.
This commit makes grid theming more consistent and capable by adding
some new theme colors related to grid rendering.
- Add grid theme color for node editor. `UI_view2d_multi_grid_draw`
is called with TH_GRID instead of a shaded `TH_BACK`.
Also color-blend `TH_NODE_GROUP`.
- Make the movie clip editor's clip preview grid respect grid theme
color (`ED_region_grid_draw` uses color-blended `TH_GRID`).
- Add versioning code to allow fixing existing themes (the resulting
themes should visually look the same as before)
These changes did cause some inconsistencies in the movie clip editor,
even after adjusting the themes accordingly:
1. The alpha slider of the grid color affects the background and not
the grid lines themselves.
2. The grids used by graph and dopesheet mode could already be themed
in the past. Now that the clip preview's grid can also be themed,
two different modes share the same theme color.

This patch reverses use draw manager for image editor the
experimental feature. Now the new drawing is enabled by default.
Inside the experimental tab in the user preferences there is now an
option to revert back to the old drawing method.
Using this option we can easilly check if all drawing features have been
migrated over. The plan is to remove the legacy drawing 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.

This replace `GPU_clear()` by `GPU_clear_color()` and `GPU_clear_depth()`.
Since we always set the clear value before clearing, it is unecessary
to track the clear color state.
Moreover, it makes it clearer what we clear the framebuffer to.
Continuing the work of eb9055a572, remove remaining unecessary
variables and arguments that were related tabbing and horizontal
alignment of panels. For example, "vertical" was always true, and
removing that exposed other unused variables.
This replaces header include guards with `#pragma once`.
A couple of include guards are not removed yet (e.g. `__RNA_TYPES_H__`),
because they are used in other places.
This patch has been generated by P1561 followed by `make format`.

The current code is accessing this from outside the gpu "namespace". As
such it should be accessing GPU_ functions, not gpu_ functions.
This is also a place to centralize the XXX message that will be
addressed upon refactor. So we can reuse this call in other places that
need the same temporary workaround.

The abbreviation 'init' is brief, unambiguous and already used
in thousands of places, also initialize is often accidentally
written with British spelling.
This is in order to disolve GPU_draw.h into more meaningful code blocks.
All the Image related function are in `image_gpu.c`.
All the MovieClip related function are in `movieclip.c`.
The IMB module now has a connection with GPU. This is not strickly
necessary and the code could be move to `image_gpu.c` if needed.
The Image garbage collection is also ported to `image_gpu.c`.
Operators are one of the last places in Blender to use older UI designs
that don't fit in with recent style conventions. This commit updates
these custom operator UI callbacks for consistency and clarity.
Some of the code is also simplified a lot. Some of the older operator layouts
were much more complex (in terms of code) than they needed to be.

Functionality here has become confusing over time,
this removes duplicate, similar functions, preferring to set the mode
instead of toggle, enter, exit.
Mode switching utility function behaved differently regarding undo,
'ED_object_mode_toggle' for example didn't skip the undo push
where 'ED_object_mode_set' did.
Some callers chose these functions based on the intended undo behavior,
even when toggling didn't make sense.
There was also ED_object_mode_generic_enter which was similar to
ED_object_mode_set, instead of the reverse of ED_object_mode_generic_exit.
Simplify object mode switching internals:
- Replace ED_object_mode_generic_enter with ED_object_mode_set.
- Remove ED_object_mode_toggle as nearly all callers needed to check
the current mode so toggling would set the mode argument correctly.
- Use ED_object_mode_set for the object mode switching operator
to simplify logic.
- Add ED_object_mode_set_ex which has an argument to disable undo,
needed when loading undo data needs to set the mode.
- Remove unused ED_object_mode_exit.
This feature was added when Blender used tex-face (per-face images),
but doesn't make as much sense since this was removed.
Removing this from UV edit-mode as this wasn't working in any
of the 2.8x releases, causing UV's to be visible but unselectable.
Resolves issue raised in T76958.
