* sw_framebuffer: Take factors into account for min/max blending
* renderer_gl: Take factors into account for min/max blending
* Address review comments
* gl_shader_gen: Fix frambuffer fetch on qcom and mali
* renderer_opengl: Add fallback path for mesa
* gl_shader_gen: Avoid emitting blend emulation if minmax_factor is present
* rasterizer_cache: Remove custom texture code
* It's a hacky buggy mess, will be reimplemented later when the cache is in a better state
* rasterizer_cache: Refactor surface upload/download
* Switch to the texture_codec header which was written as part of the vulkan backend by steveice and me
* Move most of the upload logic to the rasterizer cache and out of the surface object
* Scaled uploads/downloads have been disabled for now since they require more runtime infrastructure
* rasterizer_cache: Refactor runtime interface
* Remove aspect enum which is the same as SurfaceType
* Replace Subresource with specific structures for each operation (blit/copy/clear). This mimics moderns APIs vulkan much better
* Pass the surface to the runtime instead of the texture
* Implement CopyTextures with glCopyImageSubData which is available on 4.3 and gles.
This function also has an overload for cubes which will be removed later.
* rasterizer_cache: Move texture allocation to the runtime
* renderer_opengl: Remove TextureDownloaderES
* It's overly compilcated and unused at the moment. Will be replaced with a simple compute shader in a later commit
* rasterizer_cache: Split CachedSurface
* This commit splits CachedSurface into two classes, SurfaceBase which contains the backend agnostic functions and Surface which is the opengl specific part
* For now the cache uses the opengl surface directly and there are a few ugly casts with watchers, those will be taken care of when the template convertion and watcher removal are added respectively
* rasterizer_cache: Move reinterpreters to the runtime
* rasterizer_cache: Move some pixel format function to the cpp file
* rasterizer_cache: Common texture acceleration functions
* They don't contain any backend specific code so they shouldn't be duplicated
* rasterizer_cache: Remove BlitSurfaces
* It's better to prefer copy/blit in the caller anyway
* rasterizer_cache: Only allocate needed levels
* rasterizer_cache: Move texture runtime out of common dir
* Also shorten the util header filename
* surface_params: Cleanup code
* Add more comments, organize it a bit etc
* rasterizer_cache: Move texture filtering to the runtime
* rasterizer_cache: Move to VideoCore
* renderer_opengl: Reimplement scaled uploads/downloads
* Instead of looking up for temporary textures, each allocation now contains both a scaled and unscaled handle
This allows the scale operations to be done inside the surface object itself and improves performance in general
* In particular the scaled download code has been expanded to use ARB_get_texture_sub_image when possible
which is faster and more convenient than glReadPixels. The latter is still relevant for OpenGLES though.
* Finally allocations are now given a handy debug name that can be viewed from renderdoc.
* rasterizer_cache: Remove global state
* gl_rasterizer: Abstract common draw operations to Framebuffer
* This also allows to cache framebuffer objects instead of always swapping the textures, something that particularly benefits mali gpus
* rasterizer_cache: Implement multi-level surfaces
* With this commit the cache can now directly upload and use mipmaps
without needing to sync them with watchers. By using native mimaps
directly this also adds support for mipmap for cube
* Texture cubes have also been updated to drop the watcher requirement
* host_shaders: Add CMake integration for string shaders
* Improves build time shader generation making it much less prone to errors.
Also moves the presentation shaders here to avoid embedding them to the cpp file.
* Texture filter shaders now make explicit use of uniform bindings for better vulkan compatibility
* renderer_opengl: Emulate lod bias in the shader
* This way opengles can emulate it correctly
* gl_rasterizer: Respect GL_MAX_TEXTURE_BUFFER_SIZE
* Older Bifrost Mali GPUs only support up to 64kb texture buffers. Citra would try to allocate a much larger buffer the first 64kb of which would work fine but after that the driver starts misbehaving and showing various graphical glitches
* rasterizer_cache: Cleanup CopySurface
* renderer_opengl: Keep frames synchronized when using a GPU debugger
* rasterizer_cache: Rename Surface to SurfaceRef
* Makes it clear that surface is a shared_ptr and not an object
* rasterizer_cache: Cleanup
* Move constructor to the top of the file
* Move FindMatch to the top as well and remove the Invalid flag which was redudant;
all FindMatch calls used it expect from MatchFlags::Copy which ignores it anyway
* gl_texture_runtime: Make driver const
* gl_texture_runtime: Fix RGB8 format handling
* The texture_codec header, being written with vulkan in mind converts RGB8 to RGBA8. The backend wasn't adjusted to account for this though and treated the data as RGB8.
* Also remove D16 convertions, both opengl and vulkan are required to support this format so these are not needed
* gl_texture_runtime: Reduce state switches during FBO blits
* glBlitFramebuffer is only affected by the scissor rectangle so just disable scissor testing instead of resetting our entire state
* surface_params: Prevent texcopy that spans multiple levels
* It would have failed before as well, with multi-level surfaces it triggers the assert though
* renderer_opengl: Centralize texture filters
* A lot of code is shared between the filters thus is makes it sense to centralize them
* Also fix an issue with partial texture uploads
* Address review comments
* rasterizer_cache: Use leading return types
* rasterizer_cache: Cleanup null checks
* renderer_opengl: Add additional logging
* externals: Actually downgrade glad
* For some reason I missed adding the files to git
* surface_params: Do not check for levels in exact match
* Some games will try to use the base level of a multi level surface. Checking for levels forces another surface to be created and a copy to be made which is both unncessary and breaks custom textures

* core: Fix dynarmic use-after-free error
* bootmanager: Add current context check in DoneCurrent
* Loading a save state would destroy the frame dumper class, which contains a shared context. That context would call DoneCurrent without checking if it was actually bound or not, resulting in crashes when calling opengl functions
* externals: Correct glad readme
* common: Log renderer debug setting
* citra: Make lambda lower case
* Consistency with review comments on the PR
* video_core: Kill more global state
* GetResolutionScaleFactor would be called somewhere in the renderer constructor chain but it relies on the yet unitialized g_renderer, resulting in crashes when the resolution scale is set to auto. Rather than adding a workaround, let's kill this global state to fix this for good
* externals: Update dynarmic
* settings: Introduce GraphicsAPI enum
* For now it's OpenGL only but will be expanded upon later
* citra_qt: Introduce backend agnostic context management
* Mostly a direct port from yuzu
* core: Simplify context acquire
* settings: Add option to create debug contexts
* renderer_opengl: Abstract initialization to Driver
* This commit also updates glad and adds some useful extensions which we will use in part 2
* Rasterizer construction is moved to the specific renderer instead of RendererBase.
Software rendering has been disable to achieve this but will be brought back in the next commit.
* video_core: Remove Init/Shutdown methods from renderer
* The constructor and destructor can do the same job
* In addition move opengl function loading to Qt since SDL already does this. Also remove ErrorVideoCore which is never reached

The main advantage of switching to glad from glLoadGen is that, apart
from being actively maintained, it supports a customizable entrypoint
loader function, which makes it possible to also support OpenGL ES.
