Andrzej Kapolka	d24e340c91	To keep the frame rate up, let's only sample eight points for the blur.	2013-08-13 14:52:35 -07:00
Andrzej Kapolka	b05b43f027	Render to texture first, rather than copying from the frame buffer. Copying ... from the frame buffer requires it to have an alpha channel, which actually does something on OS X (meaning we have to set it to 1.0). We're going to want to render to texture anyway for SSAO (or other effects).	2013-08-13 12:27:52 -07:00
