Colour only, depth/stencil copy not supported.
This means that we only report pre-mod and post-mod colour values for
events. Since stencil copy is not supported, number of fragments is
not reported, and shader output is not queried.
- Refactor to use common funcs
- Add per fragment depth data
- Rename pixelhistory.frag to pixelhistory_primid.frag
- Fix how some per fragment pipelines are created
For per fragment data we create 3 pipelines
1) Post modification pipeline
changes the stencil state and scissors around the target pixel
2) Shader output pipeline
in addition to above, disables rasterization discard, depth bounds test,
culling and turns off blending
3) Primitive ID pipe
in addition to above, disables depth test and depth write, and changes
the fragment shader to only output primitive ID
* We instead always have 3rdparty/ in the relevant include search paths and rely
on that. Each library still has its own unique base dir within 3rdparty to
clarify where the include is coming from.
* We previously relied on setting the viewport smaller than the output
dimensions in D3D11 to scale for lower mips. In D3D12 the viewport is set to
the output dimensions internally so we can't do that, so instead apply a
manual scale.
The shader code is preprocessed with glslang that doesn't use the driver
capabilities to define macros indicating the availability of extensions,
instead it uses its own set of supported extensions, and in this case
it supports ARB_gpu_shader5. As a result the generated shader code would
make use of the (u)intBitsToFloat conversion functions based on the define
GL_ARB_gpu_shader5 also if the driver doesn't support this extension.
Hence an additional define is added to indicate whether bit casting
functions are available, and the extension is only enabled/required when
the driver actually supports it.
Closes: #1586
v2: - Fix ws
- reword commit message
v3: - check for ARB_shader_bit_encoding and ARB_gpu_shader5 in shader creation code
- don't enable GL_ARB_gpu_shader5 unconditionally in the OpenGL shader
- reword commit message
v4: Use an additional define HAS_BIT_CONVERSION to make sure gslang correctly
parses the shader code (Baldurk).
v6: - Add HAS_BIT_CONVERSION also with the GLES code path (Baldur)

These are not supported in GLES and causes shader compile errors when replaying a capture:
- OpenGL does not allow swizzles on scalar expressions
- implicit cast from "int" to "float"
- implicit cast from "int" to "uint"
Scalar swizzling can be replaced by vec4 and constant types can be explicitly specified.
* The histogram shouldn't be calculated as channel-wise averages, but instead by
'stacking' the channels (each channel contributes 1 to the appropriate
bucket).
* Degenerate channels (where min==max) are excluded and listed only as a single
spike, to avoid blowing out the automatic y-axis.
* We don't want to have glslang specific bits mixed in with general SPIR-V bits.
This is also preparing for moving some SPIR-V structs into common code that
can be re-used in new reflection/disassembly as well as editing.
Detected two shader compile errors while replaying GLES apps:
1. „#extension directive must occur before any non-preprocessor token” - Fix the order of precisions and extensions in the shader code.
2. „extension 'GL_OES_texture_cube_map_array' is not supported” - Do not add extensions if they are actually not supported. TEXTURE_CUBE_MAP_ARRAY was added to GLES 3.2 so GL_OES_texture_cube_map_array and GL_EXT_texture_cube_map_array are no longer used.
* Split up old uber-cbuffers used for unrelated shaders into shader-specific
cbuffers (DebugPixelCBufferData -> TexDisplayPSCBuffer / CheckerboardCBuffer /
MeshPixelCBuffer).
* Split up HLSL files so not everything is lumped into 'debugdisplay.hlsl' but
has separate files as appropriate.
* Use #include in GLSL and HLSL to better organise shader code together rather
than relying on lumping files together on the C++ side.
* Renamed files like 'debugcbuffers.h' to 'hlsl_cbuffers.h'.
* Trimmed out some extensions/cruft that isn't needed in the GLSL side since we
no longer use separable shaders.
* Combine some shaders like Outline/Checkerboard that were similar into central
place.
* It gets a couple of things less than ideal, mostly glsl block names being on
the next line, but otherwise it's readable and stops mixed tabs/spaces which
had snuck in without checks.
* Supported textures are decoded into standard format of YUVA, displayed
visually with Y in green, U in blue, V in red.
* A new texture display mode 'YUVA decode' has been added which does a default
full-range conversion from YUV to RGB.
* Custom shaders can be used to implement a custom decode matrix.
