Modified samples to test whether ANGLE can recover from a lost context....

Modified samples to test whether ANGLE can recover from a lost context.

When eglGetError returns EGL_CONTEXT_LOST, the samples now attempt to create a new EGL context and reinitialize. I haven't been able to test whether the reinitialization path works yet because ANGLE fails to make the new context current, I think because it doesn't reset the D3D device and its still in a lost state. I want to check this in though because it is a useful way of testing context lost recovery.

I also made the samples return an error code when they fail.

Why have you removed all ShutDown functions. Shouldn't you be registering those
instead?

this is not necessary anymore?

Yeah it's not needed because the samples now call eglDestroyContext, which
destroys any GL resources implicitly. I only left Shutdown functions for samples
that destroy non-GL resources.
