Optimize texture format conversion, and MethodCopyBuffer (#1274)
* Improve performance when converting texture formats.
Still more work to do.
* Speed up buffer -> texture copies.
No longer copies byte by byte. Fast path when formats are identical.
* Fix a few things, 64 byte block fast copy.
* Spacing cleanup, unrelated change.
* Fix base offset calculation for region copies.
* Fix Linear -> BlockLinear
* Fix some nits. (part 1 of review feedback)
* Use a generic version of the Convert* functions rather than lambdas.
This is some real monkey's paw shit.
* Remove unnecessary span constructor.
* Revert "Use a generic version of the Convert* functions rather than lambdas."
This reverts commit aa43dcfbe8
.
* Fix bug with rectangle destination writing, better rectangle calculation for linear textures.
