Since GLSL ES does not support the offset= attribute, struct members with explicit @align or @size attributes require adding explicit padding members. This in turn requires rewriting any constructor calls to initialize the new padding to zero, handled in the same transform. Note that this is currently overly-verbose, and will add padding where GLSL doesn't technically need it (e.g., padding a vec3 out to 16 bytes).
