From e52f1bd7b34fc73f52aadf1d33efa6685a0b22e8 Mon Sep 17 00:00:00 2001 From: Thorsten Behrens Date: Tue, 31 Jan 2012 01:07:48 +0100 Subject: Add opengl canvas implementation. Adds opengl canvas implementation - display-list-based, all rendering done as textured geometry. Needs shader support. Currently compiles and works on Linux, Mac should be ~easy to add, win32 eventually.
