- With harmonization between all texture types implemented, there is no difference between blit_engine_src and shader_read for supported formats
- Adds extra format filtering to ensure no conflicts when copying data
- Avoid silly broken tests due to queue_tag being called before pitch is initialized.
- Return actual memory range covered and exclude trailing padding.
- Coordinates in src are to be calculated with src_pitch, not required_pitch.
- Further improve aliased data preservation by unconditionally scanning.
Its is possible for cache aliasing to occur when doing memory split.
- Also sets up for RCB/RDB implementation
- After splitting, the sections may not be referenced at all for anything other than just pixel storage
- In such cases, either merge down or sample from the upstream source instead
