// RewriteStructSamplers: Extract structs from samplers.
//
// This traverser is designed to strip out samplers from structs. It moves them into separate
// uniform sampler declarations. This allows the struct to be stored in the default uniform block.
// This transformation requires MonomorphizeUnsupportedFunctions to have been run so it
// wouldn't need to deal with functions that are passed such structs.
//
// For example:
// struct S { sampler2D samp; int i; };
// uniform S uni;
// Is rewritten as:
// struct S { int i; };
// uniform S uni;
// uniform sampler2D uni_i;
