* We also fix a number of issues that could cause incorrect formats to be
generated.
* Test cases added for D3D11/GL/Vulkan to test different struct types. These
aren't automated at the moment because most of the code they're testing is in
the UI itself.
* We handle 4:4:4, 4:2:2, and 4:2:0, with packed, 2-plane and 3-plane formats,
for 8, 10, 12, and 16 bit depths.
* This covers most common formats but still leaves a few out - NV11, palettised
formats, V208/V408 JPG formats.
* This makes it easier to preview without expanding the variables, and
also clarifies the row/column distinction in a "float3x4" since it's
immediately clear how many rows there are.
* For the most part the interface is stl-compatible, but we have a few
little changes of our own for convenience.
* This class is still needed after deleting the C# UI, because we don't
want to pass C++ stl structs over module boundaries and possibly run
into hard to diagnose incompatibilities.
* There was no good reason to have a flag indicating if the special
format was valid or not. Now it's a single enum, with a value
'Regular' indicating that the compCount/compWidth/compType fully
describe the format itself.
* This makes code patterns easier as you no longer need to check for
special then check for specialFormat, you can just test the type
directly.
* Added a couple of utility macros to help with the conversion. lit() is
paired with tr() for untranslated text.
* QFormatStr is more explicitly for non-textual formatting strings.
* Both are just #define'd to QStringLiteral()
* This gives a little nicer syntax, a bit better type safety, and also
reflects better for SWIG bindings. Overall it's a minor change but
better.
* We don't update the C# UI at all, since it's soon to be removed and
not worth the effort/code churn.
* For now so we're ABI compatible with C#, all enums are uint32_t, but
that is an obvious optimisation in future to reduce struct packing.
* We avoid 'None' as an enum value, because it's a reserved word in
python so will cause problems generating bindings.
