Comment #3 on issue 168 by robhamerling: Ellipse or circle only partly drawn on GLCD
http://code.google.com/p/jallib/issues/detail?id=168
The suggestion in comment #2 is indeed a possibility, and something like this is already used in the glcd_common library (see first part of it). However sizing the variables based on the physical dimensions of the glcd works only with the assumption that nobody would ever want to draw a whole ellipse (or circle) larger than the display. But imagine when someone wants to have only part of an ellipse on the screen (and the rest clipped). In that case the variables may become too small again!
BTW: When drawing large ellipses (with a glcd_common library variant with sbyte*3 variables) funny things happen: no clipping but some sort of folding! But that maybe subject of another issue!
