I'm not saying it's easy to write shader code for all of these things to offload the bulk of the drawing work to the GPU, but it would provide a huge boost to performance.
OpenGL makes for fairly portable code, especially if you're doing something extremely narrow like rendering on a 2D texture canvas. It's only when you start to use exotic OpenGL features that you quickly get into trouble.
