[platform-ui-dev] Presentation Work

[Kim Horne <Kim_Horne@xxxxxxxxxx>]

The initial presentation work has been
committed to head.  This work aims to integrate colors, fonts, gradients
and themes into one cohesive story.  This will have the additional
benefit of greatly simplifying the workbenches use of color.  What
has been committed thus far:

• presentation categories (an umbrella under which select colors/fonts may be configured and previewed using the new org.eclipse.ui.IPresentationPreview interface)
• combined font/color preference page (Colors and Fonts) that utilizes categories and previews
• gradientDefinition children for the colorDefinition extension point.  This allows for definition of well known gradients, including their direction, component RGBs, and percentages.

Additionally, IFontProvider has been
contributed to JFace.  This label provider extension allows you to
override the font for a given element on select viewers (TreeViewer and
TableViewer at this time).
