When zooming-out hits an edge, labels & image-updates get messed up

USE CASE: WHAT DO YOU WANT TO DO?

Partially option-scroll zoom out, then see labels on the edge & scroll image.

STEPS TO REPRODUCE AN ISSUE (OR TRIGGER A NEW FEATURE)

Open large_6kx6k.txt
Make a small uncentered selection (e.g. bottom-right)
Click the zoom to selection button
Option-scroll-down to a partial zoom-out until the selection moves out from under the cursor (be sure to stop scrolling before full zoom-out is reached and where the stopping point still draws blue labels, i.e. you are still in label port mode) 5a. Hover the cursor over the top-left-most corner OR 5b. Scroll up/down

CURRENT BEHAVIOR

4: The selection box, when scrolled out to a point where it shifts out from under the cursor, the image freezes and the selection box is the only thing that moves.

5a: the column labels do not reach the left-most edge and the row labels do not reach the top.

5b: The selection box scrolls, but the image is static

EXPECTED BEHAVIOR

5a: Hovering to the top-left corner, the red highlighted labels should be above and to the left of the cursor position and the labels should generally fill the label panes.

5b: Scrolling should scroll the image in tandem with the selection box.

DEVELOPERS ONLY SECTION

SUGGESTED CHANGE (Pseudocode optional)

The option-scroll zoom out, when it hits an edge appears to behave incorrectly and must be where the problem starts. This might be a buffered image issue, but also the labels are affected, so I'm not completely sure how many sections of code need work.

FILES AFFECTED (where the changes will be implemented) - developers only

InteractiveMatrixView.java possibly more, including the buffered image classes.
