Only works on GPU backend for now, and still only supports
single-argument sample (at original coords).

Adds a new structure to describe the inputs, including type,
shape, name, etc. This removes any references to the type
variables in the compiler's context, and centralizes the
logic for parsing those type variables.
Also normalizes the rules for what types are supported.
(This was inconsistent among the various functions before).
Now:
- bool and int must be 'in'
- float may be 'in' or 'uniform'
- float[2-4] and matrices must be 'uniform'
Includes a new Slide that allows for interactive editing
of a runtime shader.
