In other words: <tt>fl_push_clip(X,Y,W,H)</tt> is applied, Another way to see what part of the image gets drawn and where, is to consider this alternative writing producing the same output:
the image is drawn with its upper-left corner at <tt>X-cx,Y-cy</tt> and its own width and height, \verbatim

Repeated calls to this member function with the same image but varying <tt>W, H, cx</tt>, or <tt>cy</tt> arguments
may be more efficiently processed using the above alternative writing.
