* 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.
* Mostly moving includes from common headers to cpp where possible, and removing
includes of the whole thing where only enums or rdcstr etc are needed.
* 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.
* Instead of baking these into the overlay texture and trying to decode them
afterwards, we instead write a grayscale 16F value into the overlay texture,
and add a special decode display mode that will use the heatmap and bucketing
provided.
* This means that saving these overlay textures now saves grayscale. When saving
to an 8-bit format, we remap to 0-255 so that greater than 1.0 values are
mapped lower.
* We were already fetching and compacting vertex buffers so this wasn't
as big a change as expected - it just needs to expand out e.g.
R16G16B16A16_SNORM to R32G32B32A32_SFLOAT so that it can be created
as a texel buffer (where the former may only be supported via fixed
function vertex inputs).
* Tweaked flycam a bit too, but not much.
* Refactored the API/C# side camera classes to avoid exposing a ton of
stuff just to do relative rotations in the arcball via quaternions.
* The arcball lookat position can also be dragged with alt-click or
middle click.
* Also supports other elements as position not just magically-selected
"POSITION" element.
* Note at the time of committing there are still some warnings in MS
headers that you might need to suppress in a couple of files.
* 3rd party code just has the warnings suppressed for ease of merging.
* The majority of warning fixes were for local variables shadowing
other locals, function parameters, or members. In most cases they
weren't a problem, but in some cases it was potentially dangerous!
* Since we decode the visual colours into an integer by looking them up
in the overdraw ramp rather than re-running to get an integer return,
we make some invisibly subtly different colours above the highest
overdraw colour, and use these to tell overdraw levels above 20.
* ie. not just an unnormalised mantissa plus biased exponent, it has proper
IEEE style float properties with hidden bit on the mantissa etc. So full
decoding is necessary, contrary to what some of the docs say :(.
* http://blog.selfshadow.com/2012/11/12/counting-quads/
* Quad Overdraw based on ScenePS4 from the revised implementation. The
colours are new, up to 20 levels. Picking pixels shows the overdraw level
* Available per-pass and per-drawcall, a pass defined the same way as in
the mesh view, drawcalls since last clear or RT change.
* List of events now passed through to RenderOverlay the same as RenderMesh
