plugins/wobblywindows: Use .toAlignedRect() instead of .toRect()

Vlad Zahorodniirequested to merge
work/zzag/wobbly-windows-to-aligned-rect into master

.toRect() doesn't work by rounding left/top/right/bottom edge coordinates. .toAlignedRect() is better suited for computing repaint regions.

CCBUG because I can't reproduce the bug.

CCBUG: 500185
