Rewritten the following global utility constants:
`umax` returns max number, restricted to unsigned.
`smax` returns max signed number, restricted to integrals.
`smin` returns min signed number, restricted to signed.
`amin` returns smin or zero, less restricted.
`amax` returns smax or umax, less restricted.
Fix operators == and <=> for synthesized rel-ops.
- Transfer writes are expected to clobber surface cache contents. Do NOT reload from CPU memory for writes.
- TODO: During transfer write to surface cache objects, lock memory if it was unlocked to avoid silly problems.
- Avoids a silly situation where a texture is discarded and an identical copy created immediately afterward.
Unfortunately allocating memory blocks is really slow so avoid it as much as possible.
- Each desc manages its own lifetime now instead of relying on global timestamp check
- Fixes situation where same object remains active without update for long
- Base the upscaling on the real source and not the "attr" parameter.
- In case of reconstruction, the source is much larger than the subslice in "attr"
- Tracks which kind of raster was done (Z-ordered vs linear) throughout the application.
- This allows to identify if data is in the expected format or not.
- Those strange offsets noted in some games seem to match to subpixel addressing.
For example, when scaling down by a factor of 4, a pixel offset of 2 will end up inside pixel 0 of the output
- In blit engine logic there is a tendancy to over-allocate so as to avoid having to sticth together textures later
- Sometimes this can lead to out of bounds access and crash applications, so memory must be validated
- Detect writes to the display output memory and handle it specially.
It already defines a known 2D region.
- Try and detect situations where raw transfers would be of benefit.
- It is possible to have a RTV<->DSV transfer with compatible-sized formats.
Mark the depth size as typeless in such a situation to avoid crossing the aspect barrier with the API.
