class PixelFormatModifier

The upper 8 bits are a vendor code. The lower 56 bits are vendor-defined.

The defined `PixelFormatModifier` values are specific, complete, and valid

values (except for `INVALID` and `DO_NOT_CARE` which have their own

meanings).

Some other valid or potentially-valid `pixel_format_modifier` values are not

defined as a `PixelFormatModifier` value, typically because the value isn't

used in practice (or potentially is newly used but not yet defined in

`PixelFormatModifier`). It is permitted to specify such a value as a

`PixelFormatModifier` value in a `pixel_format_modifier` field, despite the

lack of corresponding defined `PixelFormatModifier` value. If such a value

is used outside test code, please consider adding it as a defined value in

`PixelFormatModifier`. All such values must conform to the upper 8 bits

vendor code (don't define/use values outside the/an appropriate vendor

code).

The separately-defined `FORMAT_MODIFIER_*` uint64 values are vendor-specific

bit field values, not complete valid values on their own. These uint64

values can be used to help create or interpret a `PixelFormatModifier` value

in terms of vendor-specific bitfields.

When the `pixel_format_modifier` is set to a supported value (excluding

`DO_NOT_CARE`, `INVALID`, `LINEAR`), the arrangement of pixel data otherwise

specified by the `pixel_format` field is "modified", typically to allow for

some combination of tiling, compression (typically lossless, typically for

memory bandwidth reduction not framebuffer size reduction), transaction

elimination, dirt tracking, but typically not modifying the bit depth of the

`pixel_format`. In some cases there's a per-image or per-tile header

involved, or similar. The `pixel_format` field often still needs to be set

to a valid supported value that works in combination with the

`pixel_format_modifier`, and that `pixel_format` value can also contribute

to the overall meaning of the `ImageFormat`. In other words, the "modifier"

part of the name is more accurate than "override" would be.
