Games written using OpenGL are relatively easy to port to many platforms, and look and feel the same everywhere implementing their own UI. Web browsers have to solve a very similar problem. So, why don't we have web browsers written using the OpenGL specification? Would not having the same specification for the graphics rendering across platforms simplified development a lot? And wouldn't this also mean better rendering performance with animations utilising 3D acceleration, etc. 
A web browser written using OpenGL, is it practical?
