I have installed MaemoSDK... and it is huge - 2GB! >_< Also seems my Radeon HD 5850 with Catalyst 11.1 supports OpenGL ES using standard libGL.so(I got eglGetProcAdress from it and using this function I got all other OpenGL ES stuff). So, I will think about how will be better to add OpenGL ES implementation to ZenGL and than I will try to do some initialization stuff Rendering and so on I will add to TODO-list for ZenGL 0.3.x branch.
