JDK-5104393 - Provide d3d pipeline to improve runtime performance of Swing/2D
Description
Currently, all Swing text rendering on Windows is performed through software rasterization.  We should enable use of Direct3D textures to cache glyphs, which would improve performance in two major ways:
- every text rendering operation would become a simple textured-quad operation (and thus get hw acceleration)
- more interestingly, every AntiAliased text operation would go through the same mechanism, making it significantly faster than the current painful read-modify-write operation that translucent AA rendering currently uses.

EVALUATION We know how to do this, but the real fix will probably wait on the d3d pipeline rewrite, also due in the mustange release. ###@###.### 2004-08-20 This was indeed fixed as part of the overall d3d rewrite, as reported in bug 5104393 ###@###.### 2005-07-21 17:01:16 GMT
