Use an explicit rect, rather than center point and padding, for rect-…

…based hit tests

Prior to this patch, a rect-based hit test took as parameters a center point and four padding
values for top, right, bottom, and left padding. Theoretically, a rect-based hit test might have
asymmetric padding, but in practice, this never happens in the code (i.e., it's always true that
top-padding == bottom-padding and left-padding == right-padding).

Additionally, point-based hit tests used the same call path as rect-based hit tests (with zero
padding), which made the code hard to follow.

Finally, there was a bug in the rect-based hit test implementation: point-based hit tests always
create a one-pixel rect with the hit test point at top left and width=height=1. Because rect-based
hit tests used the same code path, the hit test rect was always erroneously expanded by one pixel
to the right and one pixel down.

This patch makes an explicit distinction between point-based and rect-based hit tests; it gets rid
of center-point-and-padding in favor of a simple rect; and it fixes the one-pixel-padding bug.
