------- Additional Comments from Xiaomei Ji <xji at chromium.org>
updated patch per Ojan's suggestion:
1. change the "if" to "switch" in RenderText.cpp for better readability
2. using dumpAsText() and textInputController.firstRectForCharacterRange(i, 0)
for layout test
3. remove pixel tests which are not necessary, and remove "font-size:2000%"
which is for pixel test only.
