GLGraphics update compatible with Processing 0148+

The opengl rendering/threading mode in Processing received some major changes in version 0148. These changes are incompatible with old releases of GLGraphics, but this is solved in the latest release, 0.8.2. This release adds a new class, GLGraphicsOffScreen, which implements off-screen rendering to texture. The downloads are available here.

Another advantage of 0.8.2 is that there is no more need of installing a hacked version of opengl.jar, so things like applets and exported applications that use glgraphics should work fine.

Off-screen fixes for ATI on OSX

A few days ago some people noted that the off-screen mode of the GLGraphics object would not work on ATI cards (see the thread in the Processing forum). A new release of the GLGraphics library (0.8.1) that fixes this issue is available for download here.

First of all, it seems to be a problem related to the opengl drivers on OSX, since I tested the off-screen rendering on a ATI 1550 on Windows XP (using catalyst drivers 6.7), and worked ok.
