    rect: Fix compiler errors about uninitialized use of variables
    
    error: 'r2.x' may be used uninitialized in this function
    
    Its happening when using gcc 5.3 with musl C library. its considering
    the case when case falls into default and immediately after exiting
    this there is a check if (r1.h > 0 && r1.w > 0) where r1 element is
    used but not assigned anything.
    
    GCC is not noticing the control flow where the initilization will
    always work due to assertion call can be a function call from libc
