plug-ins: Fix preview for Jigsaw GUI

Browse source 
After the port to gimp_procedure_dialog_get_drawable_preview (),
the preview widget was being sized to the original drawable's dimensions
while the drawable was being redrawn with only its thumbnail dimensions.
This created a scrollbar that showed unallocated/overwritten buffers.

To fix, we update the preview size and boundaries whenever the preview
is changed. This removes the scrollbar and returns to 2.10 behavior.
