[Jmol-developers] molecule display size and screen scaling

[mth <mt...@mt...>]

I have been working on the code which does drives the transformations for
rotation, zooming, and translation. By learning the code I hope to be able
to fix some of the bugs in this area.

I just checked in some code which correctly calculates the initial screen
scaling factor so that the initial zoom scaling factor is the maximum
possible size which still allows all atoms to remain completely on the
screen when the molecule is rotated. The goal is to use the window space
in its entirety without having the atoms clipped off the edge of the
window. The previous calculations were an estimate and were generally
quite a bit too small.

This is calculated & applied when the molecule is first loaded and when
the "Home" button is pressed.

I did not change the following because I want feedback from the rest of
the team:
 - the calculation of the "center" of the molecule is still the same
 - vectors/boxes are still *not* included in the calculation
 - the zoom size is not changed when the window is resized

Please give me your opinions on these items.
