    Fix undefined behavior
    
    Without the casts the bytes accesses get converted to int. but int is
    not guaranteed to be 4 bytes large. Even when it is 4 bytes large
    `bytes[3] << 24` does not fit because int is signed.

    Use fixed size integer type
    
    This type is meant to be 4 bytes large as seen in _XcursorReadUInt which
    always reads 4 bytes. An unsigned int is often 4 bytes large but this
    isnt' guaranteed so it is cleaner to use the exact type we want.
