70f55cf738 GPU: Flip the triangle front face winding if the GPU is configured to not flip the triangles. 
OpenGL's default behavior is already correct when the GPU is configured to flip the triangles.

This fixes 1-2 Switch's splash screen.

40fd6504e2 GPU: Use only the least significant 3 bits when reading the depth test func. 
Some games set the full GL define value here (including nouveau), but others just seem to set those last 3 bits.

411f04b5a4 GPU: Implement sampling multiple textures in the generated glsl shaders. 
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.

a58a06a218 GPU: Calculate the correct viewport dimensions based on the scale and translate registers. 
This is how nouveau calculates the viewport width and height. For some reason some games set 0xFFFF in the VIEWPORT_HORIZ and VIEWPORT_VERT registers, maybe those are a misnomer and actually refer to something else?

94d0d499c3 GPU: Reduce the number of registers of Maxwell3D to 0xE00. 
The rest are just macro shim registers.

219b5d34e7 GPU: Move the Maxwell3D macro uploading code to the inside of the Maxwell3D processor. 
It doesn't belong in the PFIFO handler.

dcd72b36ca Merge pull request #386 from Subv/gpu_query 
GPU: Added asserts to our code for handling the QUERY_GET GPU command.

Subv
1eca798d8b GPU: Added asserts to our code for handling the QUERY_GET GPU command. 
This is based on research from nouveau. Many things are currently unknown and will require hwtests in the future.
This commit also stubs QueryMode::Write2 to do the same as Write. Nouveau code treats them interchangeably, it is currently unknown what the difference is.

6be45c562f GPU: Support multiple enabled vertex arrays. 
The vertex arrays will be copied to the stream buffer one after the other, and the attributes will be set using the ARB_vertex_attrib_binding extension.

yuzu now thus requires OpenGL 4.3 or the ARB_vertex_attrib_binding extension.

7fe4f9491e GPU: Implemented a gpu macro interpreter. 
The Ryujinx macro interpreter and envydis were used as reference.

Macros are programs that are uploaded by the games during boot and can later be called by writing to their method id in a GPU command buffer.

f73fb9de9d GPU: Added a function to retrieve the active textures for a shader stage. 
TODO: A shader may not use all of these textures at the same time, shader analysis should be performed to determine which textures are actually sampled.

36c527131f GPU: Implement macro 0xE1A BindTextureInfoBuffer in HLE. 
This macro simply sets the current CB_ADDRESS to the texture buffer address for the input shader stage.

Subv
80b0f4d681 GPU: Implement the BindStorageBuffer macro method in HLE. 
This macro binds the SSBO Info Buffer as the current ConstBuffer.
This buffer is usually bound to c0 during shader execution.
Games seem to use this macro instead of directly writing the address for some reason.

Subv
845415cc3d GPU: Handle writes to the CB_DATA method. 
Writing to this method will cause the written value to be stored in the currently-set ConstBuffer plus CB_POS.

This method is usually used to upload uniforms or other shader-visible data.

8a5c0e873b GPU: Make the SetShader macro call do the same as the real macro's code. 
It'll now set the CB_SIZE, CB_ADDRESS and CB_BIND registers when it's called.

Presumably this SetShader function is binding the constant shader uniforms to buffer 1 (c1[]).
