gl/vk/rsx: Refactoring; unify texture cache code
gl: Fixups
- Removes rsx::gl::texture class and leave gl::texture intact
- Simplify texture create and upload mechanisms
- Re-enable texture uploads with the new texture cache mechanism
rsx: texture cache - check if bit region fits into dst texture before attempting to copy
gl/vk: Cleanup
- Set initial texture layout to DST_OPTIMAL since it has no data in it anyway at the start
- Move structs outside of classes to avoid clutter
rsx: Blit engine improvements
- Always handle blits to and from framebuffers through the GPU
- Handle depth surfaces properly when using GL
- Check for format mismatches when blitting to the surface store [WIP]
Fix rsx offscreen-render-to-display-buffer-blit surface reads
- Also, properly scale display output height if reading from compressed tile
gl: Fix broken dst height computation
- The extra padding is only there to force power-of-2 sizes and isnt used
gl: Ignore compression scaling if output is rendered to in a renderpass
rsx/gl/vk: Cleanup for GPU texture scaling. Initial impl [WIP]
- TODO: Refactor more shared code into RSX/common
- Significant gains from greatly reduced CPU work
- Also reorders command submission in end() to improve throughput
- Refactors most of the vertex buffer handling
- All vertex processing is moved GPU side
* gl: Only bind attrib textures on thread startup
* gl: Persistent mapped buffers
* gl: Fix emulated primitives in an inlined array
* gl: Do not re-update program information every draw call
* gl/vk: s1 type is signed normalized not unsigned normalized
* gl/rsx: Allow disabling of persistent buffers for debugging
gl: Large heap size is more practical
gl: Fix a bug with legacy opengl buffers
* gl/rsx: Allow emulation of unsupported attribute formats
* gl: Fix typos and remove dprints
gl: cleanup debug prints
* ui: Move the GL legacy buffer toggle to the left pane
* vk/gl: Fix cmp type, its range is [-1,1] not [0,1] SNORM_INT
