On Safari 4.0.4 and no doubt previous versions, the height of "lowercase"
letters is too short. I've found this to be the case when using ems. I don't
know if pixels render the same way.

Here are screenshots of Safari on left and Firefox 3.6b5 on right:

Make sure your browser hasn't scaled the image down so you can see this crisp…

The guides shown are based on the x-height for that paragraph (meaning
lowercase letters for the regular text--not the first line).

Although not shown, Safari and Firefox have the same exact rendering of
x-height for the regular body text. So the reference point (the spacing of
guides) is true for both browsers. Excellent!

The problem lies with how Safari renders font-variant: small caps. In this
case, the "lowercase" letters on the first line are not tall enough. You'll see
a slight gap between the top of the letters and the guide. This isn't the case
with Firefox which renders it right.

I believe that difference makes a huge difference in the practical use of small
caps in Safari.
