I am glad to do my small contribution to this nice project.
I will try to implement (port from the NXtpandedLib) new extensions (DrawCircle, DrawCircleFilled, DrawEllipse etc.) for complete MonoC# HW benchmark test but not sure that be in time at this weekend.
I have done new extensions for Lcd:
DrawCircle, DrawCircleFilled, DrawEllipse, DrawEllipseFilled, DrawRectangle
and make some improvements that allow to draw a figure even if its part is finding out of LCD.
The changes to the demo have been also added for show new features.
New commit was pushed to the same github repository:
