have two problem need to solve
1\the fonts messup when use ogre gles1 render, #1 2\nothing render when use ogre gles2 on iphone.
you can cmake the code on osx , then check to use the OGREKIT_BUILD_IPHONE and OGREKIT_COMPILE_LIBROCKET , then use the OGREKIT_BUILD_GLESRS/OGREKIT_BUILD_GLES2RS to chose gles1 or gles 2.
