    gles: Reassure compiler that uninitialized variables are not reached
    
    gcc 9 detects that if we exit this switch due to an unsupported
    pixel format, the variables that it sets will remain uninitialized,
    causing compilation with -Werror=uninitialized to fail. Treat invalid
    pixel formats the same as the ones that are already unsupported.
