* This will handle the new vulkan binding model with multiple descriptor
sets and arrays of objects in each binding. It also makes a few tidy
ups and improvements to other APIs in presentation - will e.g. now
show thumbnails for vertex and other stages.
* This fixes shader editing when the entry point file wasn't the first
in the list.
* Might need better detection of the main file than just searching for
the entry point substring - could produce false positives in other
files in a comment or #define or something similar?
* This means that all APIs pass byte string types. ALL strings everywhere
in the entire codebase must be assumed to be and treated as UTF-8 content
not ASCII.
* Gets rid of all the horrible %hs specifiers that caused warnings on
linux! Hooray.
* We convert to wide strings, or use wide characters, only when necessary
to use the Win32 API. Some windows specific code will stay in wide chars
just for convenience.
* Files are already serialised as UTF-8 strings for linux/windows binary
compatibility, so this change doesn't break backwards compatibility.
* For APIs where the shader namespace/bindpoint (which may be arbitrary
like 'the Nth texture resource' can be mapped, at each event, to the
actual API bind point where the object is.
* On D3D11 this is pass-through, on GL this returns the value of each
uniform.
* This also means GL shader reflection structures are properly immutable
and the variance in the uniform values is handled elsewhere.
* In future this might need to be expanded to support more complex binding
methods, where the mapping returns the resource rather than just mapping
to an integer bind ponit.
