* Zooms the view so that it approximates the selected region. * Fix: Zoom region marquee appears in all views.
* Tested with: - Windows 7 64-bit / Visual Studio 2010 - Ubuntu 12.04 LTS 32-bit NOTES: Zoom region works only if there are some pieces within the selected region. Since the selected region likely does not have the same aspect as the view, the zoom will fit the selected region inside the view with additional space for whichever view dimension is too long. To most accurately predict a good focus plane it is necessary to detect which object piece vertices are in the region. I dodged this complexity for now and simply use the closest vertex of any object that is in the region. Sometimes that vertex is out of region and actually closer or further than anything in region, so it will appear that the camera zoomed too far or not enough. For example, if a long brick is going from near left to far right (e.g. the default placement when you drag a 1x12 into a model) and you select the far right end, the left near end is what will be used for the focal plane and it won't quite zoom in on the right end as expected. If split views were present the selection marquee was showing in all of them simultaneously. Now it just shows in the view you are dragging on. - Rod
