Detailed Description

The Vertex struct.

Represents a vertex in the VRAM space. Its binary representation is meant to be the same as the vertices that GPU commands await. It should fit in a single register, and the MIPS ABI ought to pass it as argument or return value gracefully, making it a nice general purpose utility.

Accessors can be either {x, y}, {u, v}, {s, t}, or {w, h}, for readability purposes.

Using C++ list-initializations, one can create a vertex directly using such syntax:

Vertex{{.x = 18, .y = 42}};
