Description Dirk Schulze 2008-08-20 15:47:38 PDT
Canvas drawImage() doesn't match current specification. Negative source and destination-rects are aloud now. 
An INDEX_SIZE_ERR exception is only thrown when sw or sh are zero (like in Firefox).

drawImage() matches the specification now and exception are only thrown if sh or sw are zero (like ff).

Could only test it on gtk/cairo.
