Add patch debian/patches/fix_work_on_intel_videocards.patch: Mesa developers have enabled GL_ARB_texture_storage for all drivers [1], so i915 and i965 drivers now claim the support of this OpenGL extension, but texture storage feature does not actually work there. . [1] http://lists.freedesktop.org/archives/mesa-dev/2013-June/041188.html . This patch is just workaround to make the game work on intel videocards with new Mesa. But real problem should be fixed in Mesa. (Closes: #718680)
