Cairo port text rendering behaviour for custom fonts with and without ClearType
Overview: by default Cairo port uses CAIRO_ANTIALIAS_GRAY for text antialiasing, which results to using ANTIALIASED_QUALITY for Unicscribe text rendering on Windows platform instead of CLEARTYPE_QUALITY (corresponding Cairo antialiasing mode is CAIRO_ANTIALIAS_BEST).
Steps to reproduce:
Open any web page with embedded fonts (<a href="http://www.apple.com/mac/">http://www.apple.com/mac/</a>, for example).
Actual result: some amount of text is rendered thin and semi-transparent (as it should NOT be).
Expected result: smooth text as shown on the right side of the attachment (wincairo_text_rendering_diff.png).</pre>
