Stitcher canvas size, porportional change not bidirectional

Huh? Never noticed this.

Anyway, still reproducable in 2010.4 beta.

We might decide to call this a "won't fix", but I think for consistency we should do as "nobody" suggested.

I have two questions:-
1. Is it really a bug? (read details below).
2. If yes, then please give suggestions how I should rectify it.

Initially after looking at Panopanel.cpp[1] file especially function at Canvas Width and Height events(Line 73,74) and then looked for their respective functions i.e. WidthChange[2] and HeightChange[3], I thought there is just a typo in line 686(inside Height()) as it seemed that the author missed to include m_KeepViewOnResize as its present in WidthChange funtion), but build gave invalid parameter error for HeightChange funtion.

So, I looked for their declaration and there I saw that the original author has coded it that way( I am assuming that he meant to do it in this way only as it does seems to be *just missed it* case.).
Please see the definitions of HuginBase::PanoramaOptions::setWidth[4] and SetHeight[5].

If it needs to be modified, then please suggest me what formula's and condition should I use to modify the horizontal canvas size as I don't have much knowledge of this

Cheers
