[dev] [st][PATCH] Preserve pixelsize fractions in font defaultsize.

From: Matthew Wesley <weslem_AT_google.com>
Date: Fri, 12 Jun 2015 11:34:26 -0700

The font size is actually a double and can have non-integer values when
fonts are specified in point size instead of pixel size. Update zoom
functions to preserve the fractional component in a float. Some small
precision is lost, but the zoom reset function gets very close to the
original size and the Arg union remains 32 bits wide.
