When using the image editor the display channels attribute can become
invalid when selecting another image/buffer. This patch will check what
display channels are valid and when an invalid channel is selected it
will fall back to the color channel.
To de-duplicate the code it also introduces a
`ED_space_image_get_display_channel_mask` function that will determine
the valid bitflags for the display channel of a given `ImBuf`.
The old convention was easy to confuse with ScrArea.

This is mostly a batch rename with some manual fixing. Only single word
variable names are changed, no prefixed/suffixed names.
Brecht van Lommel and Campbell Barton both gave me a green light for
this convention change.
Also ran clan clang format on affected files.
This patch contains the work that I did during my week at the Code Quest - adding support for tiled images to Blender.
With this patch, images now contain a list of tiles. By default, this just contains one tile, but if the source type is set to Tiled, the user can add additional tiles. When acquiring an ImBuf, the tile to be loaded is specified in the ImageUser.
Therefore, code that is not yet aware of tiles will just access the default tile as usual.
The filenames of the additional tiles are derived from the original filename according to the UDIM naming scheme - the filename contains an index that is calculated as (1001 + 10*<y coordinate of the tile> + <x coordinate of the tile>), where the x coordinate never goes above 9.
Internally, the various tiles are stored in a cache just like sequences. When acquired for the first time, the code will try to load the corresponding file from disk. Alternatively, a new operator can be used to initialize the tile similar to the New Image operator.
The following features are supported so far:
- Automatic detection and loading of all tiles when opening the first tile (1001)
- Saving all tiles
- Adding and removing tiles
- Filling tiles with generated images
- Drawing all tiles in the Image Editor
- Viewing a tiled grid even if no image is selected
- Rendering tiled images in Eevee
- Rendering tiled images in Cycles (in SVM mode)
- Automatically skipping loading of unused tiles in Cycles
- 2D texture painting (also across tiles)
- 3D texture painting (also across tiles, only limitation: individual faces can not cross tile borders)
- Assigning custom labels to individual tiles (drawn in the Image Editor instead of the ID)
- Different resolutions between tiles
There still are some missing features that will be added later (see T72390):
- Workbench engine support
- Packing/Unpacking support
- Baking support
- Cycles OSL support
- many other Blender features that rely on images
Thanks to Brecht for the review and to all who tested the intermediate versions!

flipped to bottom
While flipping the header to bottom works in the MCE (because MCE doesnt
allow overlapping UI) we need to take the regions visible rect into
account for the Image Editor.
Also correct clickable scubbing area (poll for frame_change) in the
Image Editor and the MovieClip Editor not taking UI_DPI_FAC into
account.

Images were being freed often because the tagging for when the image was last
used was missing.
Differential Revision: https://developer.blender.org/D5252
since header regions can possibly overlap, accommodate by getting main
regions visible rect first.

BF-admins agree to remove header information that isn't useful,
to reduce noise.

This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.
See P901 for script to perform these edits.
This is in order to make the API more multithread friendly inside the
draw manager.
GPU_shader_get_uniform will only serve to query the shader interface and
not do any GL call, making it threadsafe.
For now it only print a warning if the uniform was not queried before.
This translates the gl calls to the new GPU_ wrappers from D3501.
Given it's tedious and repetitive work, this patch does as much as it can with search + replace, the remainder of the gl calls will need to be manually dealt with on a case by case basis.
This fixes 13 of the 28 failing editors when building without opengl.

This commit does two things:
- Adds an option to do the calculation in different color spaces (BT601
or BT709).
- Changes the default caluclation from legacy BT601 to BT709.
This affects several areas:
- UI areas (mainly scopes)
- ViewLevelsNode
- Several other nodes that use `COM_ConvertOperation.h`
- Use BLI_threadpool_ prefix for (deprecated)
thread/listbase API.
- Use BLI_thread as prefix for other functions.
See P614 to apply instead of manually resolving conflicts.
