Fixes #122
- In cases with an explicit mip level being specified, there was a mistake in how the argument for setting the mip level in the GLSL code was constructed that led to a parse error in GLSL
- Also, that argument is a `uint` in HLSL and an `int` in GLSL, so an explicit cast was needed
- The GLSL functions here seem to require a newer GLSL (at least higher than `420`), so I had to add in a capability for builtins to specify a required GLSL version. For now I made these ones require `450`.
- Added a test case to confirm that our lowering works (for some definition of "works")

Fixes #103
- Previously I was relying on scalar-to-vector promotion to pick the right type in these cases, but I hadn't implemented scalar-to-matrix promotion (I should...)
- Rather than relying on promotion behavior, this change goes ahead and adds explicit overloads. I think this is probably a better decision in the long term, since one might want to support these cases for operators, while warning (or erroring) on the more general cases of implicit conversion.
- This covers matrix/scalar, scalar/matrix, vector/scalar, and scalar/vector cases

Fixes #75
In order to avoid cascaded errors, I went ahead and made the parser refuse to skip past a `}` in recovery mode. The problem with this is that we fail to make forward progress if we are stuck on a `}` (this happens if you have an extra `}` at the global scope.

Fixes #34.
I'd declared these as if they were `InputPatch<T>`, but they are really `InputPatch<T,N>`.
This change fixes the declarations, and makes these types no longer inherit from the contrived `BuiltinGenericType`.
Instead they are more-or-less ordinary `DeclRefType`s using the same approach that `MatrixExpressionType` uses.
