From 56d920a5c1b64868e77a97604c01d3a63916a6ca Mon Sep 17 00:00:00 2001 From: Alexander von Gluck IV Date: Sat, 14 Dec 2013 11:46:05 -0600 Subject: [PATCH] Haiku: Add in public GL kit headers * These make up the base of what C++ GL Haiku applications use for 3D rendering. * Not placed in includes/GL to prevent Haiku headers from getting installed on non-Haiku systems.
