The code to convert to bitmap allocates the bitmap and draws to the bitmap. In
the actual application you can draw directly to the canvas DC in the on-paint
method, which would save a bitmap allocation and an intermediate draw step.

looking at these designs, I think by the time you're done writing code that
draws directly to a dc, the code will be just as slow as the pict code, and
probably with more bugs.
Also, it seems you are rendering about 20 designs on the page.
How long does it take to render an actual quilt design?
