Some games (GameMaker Studio) build texture atlases out of sprites during initialization, using the 2D copy method. These copies are done from textures loaded into memory, not rendered, so they are not scaled to begin with.
I had set srcTexture in these copies to force scaling, but really it only needs to scale if the texture already exists and was scaled by rendering or something else. I just set that to false, so it doesn't change if the texture is scaled or not. This will also avoid the destination being scaled if the source wasn't. The copy can handle mismatching scales just fine.
This prevents scaling artifacts in GMS games, and maybe others (not Super Mario Maker 2, that has another issue).
* Lift textures in the AutoDeleteCache for all modifications.
Before, this would only apply to render targets and texture blit. Now it applies to image stores, the fast dma copy path and any other type of modification.
Image store always at least has one reference in the texture pool, so the function of the AutoDeleteCache keeping textures _alive_ is not useful, but a very important function for a while has been its use to flush textures in order of modification when they are dereferenced, so that their data is not lost.
Before, textures populated using image stores were being dereferenced and reloaded as garbage. Now, when these textures are dereferenced, their data will be put back into memory, and everything stays intact.
Fixes lighting breaking when switching levels in THPS1+2, and potentially some more UE4 games. I've tested a bunch more games for regressions and performance impact, but they all seem fine.
* Lift copy srcTexture so that it doesn't remain referenceless
* Perform lift before reference count change on unbind.
It's important to lift on unbind as that is the moment the texture was truly last modified, but definitely not after releasing every single reference.
* 3D engine now uses DeviceState too, plus new state modification tracking
* Remove old methods code
* Remove GpuState and friends
* Optimize DeviceState, force inline some functions
* This change was not supposed to go in
* Proper channel initialization
* Optimize state read/write methods even more
* Fix debug build
* Do not dirty state if the write is redundant
* The YControl register should dirty either the viewport or front face state too, to update the host origin
* Avoid redundant vertex buffer updates
* Move state and get rid of the Ryujinx.Graphics.Gpu.State namespace
* Comments and nits
* Fix rebase
* PR feedback
* Move changed = false to improve codegen
* PR feedback
* Carry RyuJIT a bit more
* Use DeviceState for compute and i2m
* Migrate 2D class, more comments
* Migrate DMA copy engine
* Remove now unused code
* Replace GpuState by GpuAccessorState on GpuAcessor, since compute no longer has a GpuState
* More comments
* Add logging (disabled)
* Add back i2m on 3D engine
