Hi,
I have found a bug when do scrolling with a2dCanvas, if you scroll with
a reverse direction as last scroll, for e.g. you press PAGE_DOWN and then
press PAGE_UP, the scroll thumb will move to wrong position, it behaves like
you press PAGE_DOWN again.
I have investigate the code, and found it could be fixed by minor
changes with a2dCanvas::ScrollWindowConstrained()
Following are the output of the cvs diff command
D:\Src\wxArt2D\modules\canvas\src>cvs diff canvas.cpp
