Zoom to box is broken

This has been going on forever, here is now the master bug. I will close the others as duplicates.

This one is becoming important. I have yet another user frustrated with this incorrect behavior. We are losing customers due to the poor zooming of this feature.

Here are testing cases that fail, that I want to work:

  • 5.4.0, Linux, local server.
  • Tools/ Lock View Size Custom. 1920x1080. OK.
  • Sources/ Sphere. Surface with Edges. Apply.
  • Perspective sphere full
  • Reset.
  • Zoom to box selection. Select from upper left to lower right. Include a small amount of background above, below, left and right.
  • We will zoom in too far. The top and the bottom of the sphere have disappeared. This is a bug.
  • Solution - If the ratio of the view size vs the selection is larger horizontally, zoom the selection by the vertical amount. In other words, always make the selection fit - even if there is extra on the edges.
  • Perspective sphere edge
  • Reset. +Z.
  • Zoom to box selection. Start selection from 1/2" left of and above the left most point of the sphere. Rubber band select to about 1/2" right and below of this point. In other words, make a 1" X 1" selection around this left most point.
  • We will not be centered on the point. The background to the left has disappeared. This is a bug.
  • Solution - Place the center of the selection in the middle of the view. Same as above - If the ratio of the view size vs the selection is larger horizontally, zoom the selection by the vertical amount. In other words, always make the selection fit - even if there is extra on the edges.
  • Turn off Camera Parallel Projection (This is a advanced Property).
  • Orthogonal sphere full
  • Same problem as perspective. Zoom is wrong.
  • Orthogonal sphere edge
  • This appears to be working correct. But, test.
