Switch RenderTextMac to use point font sizes instead of pixel font sizes.

Switch RenderTextMac to use point font sizes instead of pixel font sizes.

The previous implementation tried to use pixel sizes for consistency with
implementations of RenderText on other platforms. However, it turns out
that Skia itself uses point font sizes on Mac as does gfx::Font, so it
makes more sense to use point sizes throughout.

BUG=125664, 137033
TEST=Patch in http://codereview.chromium.org/10879069/ and bring up a
print preview on www.google.com. Letter spacing for the header and
footer text should be the same as what's produced by current Canary.

You can check who/reviewerlogin/calendar to check if someone is out of office
when they take longer to review than expected. I was out Friday.

No worries.
