-// Thoughts on the implementation of a vertex loader compiler.
-// g_vertex_manager_write_ptr should definitely be in a register.
-// Could load the position scale factor in XMM7, for example.
-
-// The pointer inside DataReadU8 in another.
-// Let's check out Pos_ReadDirect_UByte(). For Byte, replace MOVZX with MOVSX.
