This fixes: 1. A compilation error when assigning scalars to matricies 2. A semantic error in matrix construction from scalars. This was initializing the diagonal, where HLSL semantics require the scalar be replicated to every matrix element. 3. Functions accepting mats can be called with scalars, which will be shape-converted to the matrix type. This was previously failing to match the function signature. NOTE: this does not yet handle complex scalars (a function call, say) used to construct matricies. That'll be added when the node replicator service is available. For now, there's an assert. There's one new test (hlsl.scalar2matrix.frag). An existing test lsl.type.half.frag changes, because of (2) above, and a negative test error message changes due to (3) above. Fixes #923.
