and scale the breakpoint dots accordingly - now they don't looked all
squashed anymore.
I think ResizeImageList() is more correct now, at least this helped with
the breakpoint dots.
but it's still a bit wonky with DPI-scaling
I also made the rect calculations a bit more intuitive
and removed a misleading comment in my breakpoint list code
Double-clicking an entry opens the script at the correct line.
Single-clicking the breakpoint symbol in the list removes the breakpoint,
and so does selecting the breakpoint in the list and pressing the Del key.
Editor also seems to start, didn't test much further.
Only tested 32bit Windows, I fear the editor code isn't 64bit clean..
I hope I haven't broken anything elsewhere..
