Hi Alexandros, clutk/ctk-gfx-private.c: yes, "CHECKGL( glEnable (GL_TEXTURE_2D) );" can be removed, because GL_TEXTURE_2D is always enabled by default in gles2. clutk/ctk-gfx-private.h: I don't think we need to include or here. Any reason for this? configure.ac: Good catch. :) Regards, Jammy 2010/9/21 Alexandros Frantzis
