1) Why CPU? Mainly we used CPU because it's easier to get working. A lot of this graphics stuff requires deep understanding. It’s just easier to get CPU mode running. I do have many GPU experiments though. I even have a macro that translates a subset of Nim into the GLSL - GPU’s shader language. In time if the GPU path becomes better we will switch to it.

2) Yes, Pixie will render Fidget. Current system is that Pixie renders to a texture atlas. Then Fidget just deals with the textures. Pixie does work only at “load time” or when a new element comes on screen. For most screens Pixie CPU rendering will not be called that often. At this time the CPU render for text is faster than my on-the-GPU render. More things will switch to GPU as it becomes faster.

3) I am still working on Fidget, but I really wanted to get Pixie done first. I have this idea that I am exploring. But I don’t have anything for sure yet. One thing for sure Fidget 2 will be a total paradigm ship from Fidget 1. But Fidget 2 is still ways off.
