canvas-base: Do not attempt useless cast on stride adjustment

Browse Source 
memmove already deal with any alignment so there's no
reason to have row byte pointer cast to uint32_t.
This also remove the confusing "dest" terminology used. The image
is aligned in place so the image bits are used for both destination
and source.
