Comment #1 on issue 168 by robhamerling: Ellipse or circle only partly
drawn on GLCD
http://code.google.com/p/jallib/issues/detail?id=168
Slight correction: the distortion appears already on a 128x64 glcd drawing
an ellipse from side to side and top to bottom, or even somewhat smaller.
Analysis shows that with larger radii some variables in the procedure
glcd_ellipse() in library glcd_common.jal may overflow. Declaring these
variables as 'sbyte*3' in stead of 'sword' solves the problem.
This may seem overkill for smaller displays, but since library glcd_common
is supposed to work for all glcd's there is little choice...
Maybe the variables should even be declared as sdwords to support really
large glcds.
