Zooming what ?

[Krzysztof Foltman <kfoltman onet pl>]

Another idea, inspired by working ctrl+scroll patch:

Change Zoom tool so that it preserves a zoom point.

I mean: now, when you zoom in a graph by clicking a zoom tool or 
ctrl+wheel, the graph point at screen location of the cursor is 
displayed at window's center point.

I'd like the graph point at screen location of the cursor to be 
displayed... at screen location of the cursor (and not middle of the 
window). So you still point to the same item on the graph as you pointed 
before zooming.

Does that make sense ? I think it makes multiple zoom operations in 
sequence behave more consistent (even if you ocassionally need to pan to 
put the pointed thing in the middle).

Alan (which I discussed the idea with) also suggested to make zoom 
center on selected objects - maybe that would make sense for non-tool 
zooming (the option button one).

Any suggestions ?
