Lioncash 14e0b48ae4 VideoCommon: Make API_TYPE an enum class
Allows for forward declarations in most places, which prevents dumping
unrelated VideoCommon.h contents directly into headers.

Scott Mansell 24e5d21780 Multithreadded Shadergen: Second pass over Pixel Shadergen.
Note: It's not 100% perfect, as some of the GPU capablities leak into the
pixel shader UID.

Currently our UIDs don't get exported, so there is no issue. But someone
might want to fix this in the future.

Scott Mansell 1a831cfc7d Multithreadded Shadergen: Second Pass over vertex/lighting Shadergens
As much as possible, the asserts have been moved out of the GetUID
function. But there are some places where asserts depend on variables
that aren't stored in the shader UID.

Scott Mansell 4969415f38 Remove global refrences from common code.
Bug Fix: Previously vertex shaders and geometery shaders didn't track
         antialaising state in their UIDs, which could cause AA bugs
	 on directx.

Scott Mansell 0d996f512b Multithreadded Shadergen: First pass over pixel Shadergen
Bug Fix: It was theoretically possible for a shader with depth writes
         disabled to map to the same UID as a shader with late depth
	 writes.
	 No known test cases trigger this.

Scott Mansell e99364c7c9 UID Change: Fix bug with indirect stage UIDs
Bug Fix: The normal stage UIDs were randomly overwriting indirect
         stage texture map UID fields. It was possible for multiple
	 shaders with diffrent indirect texture targets to map to
	 the same UID.
         Once again, it dpesn't look like this bug was ever triggered.

Scott Mansell 03f2c9648d Shader UID change: Only store the two bits of components we need.
This frees up 21 bits and allows us to shorten the UID struct by an entire
32 bits.

It's not strictly needed (as it's encoded into the length) but I added a
bit for per-pixel lighiting to make my life easier in the following
commits.

Scott Mansell 53c402dbc5 Multithreadded Shadergen: First Pass over vertex/lighting Shadergens
The only code which touches xfmem is code which writes directly into
uid_data.

All the rest now read their parameters out of uid_data.

I also simplified the lighting code so it always generated seperate
codepaths for alpha and color channels instead of trying to combine
them on the off-chance that the same equation works for all 4 channels.

As modern (post 2008) GPUs generally don't calcualte all 4 channels
in a single vector, this optimisation is pointless. The shader compiler
will undo it during the GLSL/HLSL to IR step.

Bug Fix: The about optimisation was also broken, applying the color light
         equation to the alpha light channel instead of the alpha light
	 euqation. But doesn't look like anything trigged this bug.

degasus 10e4f7e7bf PixelShaderGen: Move constant multiplication to constant generation.
No need to do this within the shader per pixel if it can be done once.

Stenzek e6b2212ec0 ShaderGen: Only specify storage qualifier in interface block when needed
Drivers that don't support GL_ARB_shading_language_420pack require that
the storage qualifier be specified even when inside an interface block.

AMD's driver throws a compile error when "centroid in/out" is used within
an interface block.

Our previous behavior was to include the storage qualifier regardless, but
this wasn't working on AMD, therefore we should check for the presence of
the extension and include based on this, instead.

Ryan Houdek 3ab7806e24 Workaround OS X video driver bug #24983074
OS X's shader compiler has a bug with interface blocks where interface block members don't properly inherit the layout qualifier from the interface
block.
Work around this limitation by explicitly stating the layout qualifier on both the interface block and every single member inside of that block.

Jules Blok 9805f70913 VideoConfig: Replace FastDepthCalc by ForcedSlowDepth.
Fast depth is now more accurate than slow depth and should always be used.
The option will be kept in a different form as it is still used as a hack to fix some games.
Also, the slow depth code path will still be relied upon by cards that don't support GL_ARB_clip_control.

Stenzek edebadc093 PixelShaderGen: Use bitwise AND for wrapping indirect texture coordinates
(x % y) is not defined in GLSL when sign(x) != sign(y).
This also has the added benefit of behaving the same as sampler wrapping modes, in regards to negative inputs.

Stenzek 617f9d9532 ShaderGen: Remove virtual methods from ShaderGeneratorInterface, move string buffer to ShaderCode
This fixes the crashes occuring at startup with a non-empty shader cache.
Because LinearDiskCache reads/writes to the storage of ShaderUid, ShaderUid must be trivially copyable.
Additionally, adds a static assert to LinearDiskCache to ensure this doesn't happen in the future.

The initialization of ShaderUid data has been moved to the code generation functions, so the above condition holds true.

Ryan Houdek c1df6d7b4e Work around PowerVR's shader compiler.
This bug has been reported to IMGTec at https://pvrsupport.imgtec.com/ticket/472

The basic idea of the bug is that if you're doing a bitwise and  of a constant value vector with a constant scalar value, this causes PowerVR's shader
compiler to fail out with a very non-descriptive message.
Working around the issue by making the value a vector that it is being masked by.
