Uniform buffer uniform unpacking utility function
When data is packed into uniform blocks, some data isn't formatted in
a way that fits how data is usually represented, which is the case
for booleans and row major matrices. In these 2 cases, the variables
are unpacked into temporaries before being used. Booleans can be any
integer value and any non-zero value represents "true", so the value
in the uniform buffer has to go through an int to bool conversion
before being used. For row major matrices, a given register of that
matrix has to be transposed into a temporary before being used.
