modules/pixbounce: use float for multiplier

The lack of support for fractional multipliers prevents pixbounce
from drawing anything in small frame scenarios, like as a
checkers fill_module.

You can easily reproduce this by doing:
--module=pixbounce,pixmap_size=0.8,pixmap=err --video=sdl,size=64x64 --defaults --go

Which after this commit works...

While here I did a minor optimization removing some divides, and
fixed up the assumption that fragment->{width,height} ==
fragment->frame_{width,height} in pixbounce_prepare_frame().
It should have been using .frame_{width,height}.
