Hack to pretend EXT_bindable_uniform is supported
It looks like most of Dungeon Defenders' shaders try to enable
EXT_bindable_uniform via:
#extension GL_EXT_bindable_uniform : require
but all of the shaders also contain "/*ndabl*/uniform" instead of "bindable
uniform", which suggests that the game /used/ to use the extension, but doesn't
now. It's just asking for functionality it doesn't need.
I commented on the upstream bug (linked from the URL field here); hopefully
icculus can fix that. In the meantime, I've also attached a patch that makes
Mesa pretend to support the extension, which allows the game to run. (It
doesn't actually implement anything.)
On i965/Ivybridge, this makes it draw the splash screen, but it then hits an
assertion failure. I'll look into that.</pre>
