Let me clarify.
There will be various graphic images in the bitmap that he user can
grab handles on and resize.
There will be simulation of stitching (as in sewing machine) going on.
These are all calculated / created in underlying portable code (we use
it in Windows).

I'm not sure what your app does, but have you considered using a
Core Animation layer to host the bitmap? That way you can move the
image around willy-nilly with virtually zero cost, and you only have
to regenerate the bitmap if it changes.
