This is entirely unused and can be removed.

Currently we only have an OpenGL renderer, so this is unused in code
(and occupies the Renderer identifier in the VideoCore namespace).

dynarmic: Update to 0118ee0

Implements VertexAttributes Size_32_32_32 and Size_8_8.

- Used by Super Mario Odyssey.

gl_rasterizer_cache: Remove unused viewport parameter of GetFramebufferSurfaces()

Revert "gl_state: Temporarily disable culling and depth test."

textures: Refactor out for Texture/Depth FormatFromPixelFormat.

0118ee0 emit_x64_vector: packusdw is SSE4.1

gl_rasterizer_cache: Add bounds checking for gl_buffer copies.

core: Make function reference parameters const where applicable

common/logging: Add missing service log categories

 fsp_srv: Emplace entries first when building index instead of emplacing last

gl_shader_decompiler: Reserve element memory beforehand in BuildRegisterList()

vfs: Add VfsFilesystem and fix RealVfs* implementations

maxwell_3d: Ignore macros that have not been uploaded yet.

* Implement BC5/DXN2 (#996)

- Used by Kirby Star Allies.

* Implement BC5/DXN2 SNORM

UNORM for Kirby Star Allies
SNORM for Super Mario Odyssey

gl_rasterizer_cache: Avoid iterator invalidation issues within InvalidateRegion()

Avoids potentially perfoming multiple reallocations when we know the
total amount of memory we need beforehand.

A range-based for loop can't be used when the container being iterated
is also being erased from.

gl_shader_decompiler: Declare predicates on use.

gl_rasterizer_cache: Use std::vector::assign vs resize() then copy for the non-tiled case

Implement VertexAttribute::Size::Size_16_16_16_16 and PrimitiveTopology::Points.

gl_rasterizer: Do not render when no render target is configured.

- Used by Kirby Star Allies.

This is simply copied by value, so there's no need to make it a
modifiable reference.

While we're at it, make the names of the parameters match its
definition.

This function doesn't modify anything within the reference Thread
instance.

common/color: Minor cleanup

gl_rasterizer_cached: Implement RenderTargetFormat::B5G6R5_UNORM.

It's generally easier to follow code using conditionals that operate in
terms of the true case followed by the false case (no chance of
overlooking the exclamation mark).

resize() causes the vector to expand and zero out the added members to
the vector, however we can avoid this zeroing by using assign().

Given we have the pointer to the data we want to copy, we can calculate
the end pointer and directly copy the range of data without the
need to perform the resize() beforehand.

vector_math: Use variable template version of is_signed in Vec classes
