Android OpenGL ES 2 context creation bug and fix

On an OpenGL ES 2 capable device, it is not enough to pick a config that supports ES2, it is necessary to specify an EGL_CONTEXT_CLIENT_VERSION of 2 when one is wanted… I have revised the
eglCreateContext call as shown below in my local copy.

I also think the eglChooseConfig is busted, the first config reported on my device has EGL_DEPTH_SIZE 0 which makes it rather useless for a 3D game, I uncommented the request for EGL_DEPTH_SIZE 16 in
my local copy for this purpose, the alternative would be to request a large number of configs (I got over 20 unique ones in testing… so a larger number is required) and picking the “best matching” one.

This is just a bland snippet of revised code for android-project/src/org/libsdl/app/ - sorry for any inconvenience with it not being a directly applyable patch.

         int EGL_CONTEXT_CLIENT_VERSION=0x3098;
         int contextAttrs[] = new int[]
             EGL_CONTEXT_CLIENT_VERSION, majorVersion,
         EGLContext ctx = egl.eglCreateContext(dpy, config, EGL10.EGL_NO_CONTEXT, contextAttrs);--
