This is my rough idea about how the drawing systems works with the paint
partial:
0. When buffers are not being used paint uses paintPartial to do the
painting
1. paintState==0 under normal conditions triggers an update with the
calculated dt (++frame)
1a. This recomputes all the solar system object positions and the the
tansformation matrices and the FOV
2. paintState==1 triggers drawing using the drawPartial function
2a. Do the preDraw in the core
2b. Draw 1 module per iteration
2c. Do the postDraw in the core
The callee for the paint function i think is the updateScene.
The mentioned increase in FPS must be when there has been an event in the
last 2.5 seconds right. Else it must return to minFPS
I dont understand how this process allows for doing the calculation over
several frames. Is it not that the all calculation happens in step 1 at one
go and that no display can happen till step 2. And then it keeps doing the
drawing till the end.

You can't have everything in life,
In particular, the list of all lists that do not contain themselves.
