Uniform block declaration
A few aspects of block declaration are improved upon here:
- Block definitions are computed and stored for later use.
The data stored are the block member types and a map to
convert from register offsets, based on the internal
memory layout, to the std140 layout.
- Declaration of block members is possible. When a block
member is declared prior to the entire block being
declared, OutputASM::declareUniform() will first declare
the whole block and return the index of the block member.
If the block member is part of an already defined block,
the function declares no new variables and returns the
block member's register index.
