/*
VRAM invalidation tracking
- we want to know when a VRAM region used for graphics changed
- for some regions unmapping is mandatory to modify them (Texture, TexPal and ExtPal) and
we don't want to completely invalidate them every time they're unmapped and remapped
For this reason we don't track the dirtyness per mapping region, but instead per VRAM bank
with VRAMDirty. Writes to LCDC go directly into VRAMDirty, while writes via other mapping regions
like BG or OBJ are first tracked in VRAMWritten_* and need to be flushed using SyncDirtyFlags.
This is more or less a description of VRAMTrackingSet::DeriveState
Each time before the memory is read two things could have happened
to each 16kb piece (16kb is the smallest unit in which mappings can
be made thus also the size VRAMMap_* use):
- this piece was remapped compared to last time we checked,
which means this location in memory is invalid.
- this piece wasn't remapped, which means we need to check whether
it was changed. This can be archived by checking VRAMDirty.
VRAMDirty need to be reset for the respective VRAM bank.
