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

GPU: Implement the ISET family of shader instructions.

GPU: Stub the SSY shader instruction.

gl_shader_decompiler: Implement SHR instruction.

gl_shader_decompiler: Implement IADD instruction.

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

Enable ccache usage on Travis

Common/string_util: add StringFromBuffer() function

GPU: Fixed ghosting when drawing with blending disabled

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.

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

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.

Ubuntu 18.04 already has cmake 3.10.2

Use Ninja for Travis builds

GLRenderer: Write the shader stage configuration UBO data *before* copying it to the GPU.

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

Service/MM: add service and stub some functions

gl_shader_decompiler: Implement BFE_IMM instruction.

GLCache: Fixed copying compressed textures in the rasterizer cache.

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.

gl_shader_decompiler: F2F: Implement rounding modes.

Service/nfp:user : stub some functions.

gl_shader_decompiler: Additional decodings, remove unused stuff from TEX

GPU: Support changing the texture swizzles for Maxwell textures.

gl_shader_decompiler: Implement ISETP_IMM instruction.
