WebGL, at last!

It's been a long time since I've written an update -- but my lack of blog posting is not an indication of a lack of progress in WebKit or the WinCairo port. Since I left my former employer (who *still* hasn't gotten around to updating the build machine I set up there), we've:

• Migrated from Visual Studio 2005 to Visual Studio 2010 (and soon, VS2012)
• Enabled New-run-webkit-tests
• Updated the WinCairo Support Libraries to support 64-bit builds
• Integrated a ton of cURL improvements and extensions thanks to the TideSDK guys 
• and ...

... thanks to the hard work of Alex Christensen, brought up WebGL on the WinCairo port.  This is a little exciting for me, because it marks the first time (I can recall) where the WinCairo port actually gained a feature that was not already part of the core Apple Windows port.

The changes needed to see these circa-1992 graphics in all their three-dimensional glory are already landed in the WebKit tree.  You just need to:

1. Enable the libEGL, libGLESv2, translator_common, translator_glsl, and translator_hlsl for the WinCairo build (they are currently turned off).
2. Make the following change to WTF/wtf/FeatureDefines.h:

Performance is a little ragged, but we hope to improve that in the near future.

We have plenty of more plans for the future, including full 64-bit support (soon), and hopefully some improvements to the WinLauncher application to make it a little more useful.

As always, if you would like to help out,
