07.feedback example: window creation messed up.
by B. Bogart 12 Jan '11

12 Jan '11

Hey Gem Devs, Seems someone changed the gemwin creation stuff in the 07.feedback example. Unfortunately this breaks the patch, or rather makes the output ugly and non illustrative of feedback. The patch is intended for a 512x512 window with lighting on. Seems the "gemwin" abstract does not (easily) allow these things. So why was it changed in the first place? Thanks, B.
