I created a nice documentation about managing states. Some of this information was already available, but scattered over the manual and not so clearly organized. The new page should serve as a clear documentation how states are supposed to be used. We have a nice list of TCastleTransform descendants with screenshots in the manual page …

I added and to easier load designed UI in , and even see the designed UI in Lazarus form inspector. The short documentation is added to TCastleControl chapter. Our engine examples examples/lazarus/model_3d_with_2d_controls and examples/lazarus/two_controls use it already.
