Title: Adjust the values of a dirty rectangle that has negative values

When a DisplayNode object has negative scale values, its dirty rectangle has negative width or height. Unfortunately, my renderer cannot create a clip rectangle that covers it for this case. This change changes the position (and size) of a dirty rectangle that has negative values to fix this problem.
