It was crashing and nobody actually uses this.

Only tiled->linear and linear->tiled copies that aren't offsetted are supported for now. Queries are not supported. Swizzled copies are not supported.

This corrects the invalid position values in some games when doing attribute-less rendering.

This instruction tells the GPU where the flow reconverges in a non-uniform control flow scenario, we can ignore this when generating GLSL code.

Only independent blending on render target 0 is implemented for now.

This fixes the elongated squids in Splatoon 2's boot screen.

GLCache: Align compressed texture sizes to their compression ratio, and then align that compressed size to the block height for tiled textures.

This fixes issues with retrieving non-block-aligned tiled compressed textures from the cache.

Rasterizer: Flush the written region when writing shader uniform data before copying it to the uniform buffers.

This fixes the flip_viewport uniform having invalid values when drawing.

This should fix the bug with the vs_config UBO being uninitialized during shader execution.

convert input buffer (std::vector<u8>) to string, stripping zero chars

This avoids the problem of only copying a tiny piece of the textures when they are compressed.

We now use glCopyImageSubData, this should avoid errors with trying to attach a compressed texture as a framebuffer's color attachment and then blitting to it.

Maybe in the future we can change this to glCopyTextureSubImage which only requires GL_ARB_direct_state_access.

All tested games that use a single texture show no regression.

Only Texture2D textures are supported right now, each shader gets its own "tex_fs/vs/gs" sampler array to maintain independent textures between shader stages, the textures themselves are reused if possible.

* add IoctlCommands with their params in nvidia_ctrl_gpu.h

* add function related to the changes done previously

* fix clang-format

* delete trailing whitespace

* correct mistake

* GDB Stub should work now.

* Applied clang-format.

* Replaced htonll with swap64.

* Tidy up.
