Subject: [PATCH] Round text coordinates consistently.

The core implementation used parseInt, which was originally to catch
text values, but really only stayed due to its side-effect of flooring
the values.  The canvas implementation has never rounded coordinates.
This led to various one-pixel rendering glitches between the two
implementations.  I've fixed the problem by consistently rounding
coordinates to the nearest whole number.
