This is a small but imo useful patch that makes TGE or TGB create framebuffers with alpha channels.
You can query whether the current framebuffer has an alpha channel by querying gGLState.suppAlphaBuffer.
The smooth HUD borders in Shelled/GravGolf were only possible with alpha buffer support:
(I'm cross-linking to Joshua's GravGolf screenshots here.)
Simply apply the patch using patch -p0 -i alphaframebuffer.diff in the engine/source dir or use SVN Tortoise's "Apply Patch.." feature.
This patch was both tested with TGE 1.4.2 and TGB 1.1.3.

With this patch the framebuffer gets an alpha channel, too, so you can render to it and create more advanced alpha blending effects. Without it alpha blending always behaves as if the dst flag was GL_ONE.Cheers,
