Environment

Second Life Release 7.2.3.19375695301 (64bit)
Windows 11 / Mac

Description

Reset the snapshot capture size when a Cancel button is clicked.

Reproduction steps

1. Choose World > Snapshot. Note that the size at the bottom of the floater is the size of the Second Life window.
2. Click the Save to Inventory button.
3. Notice the image defaults to Small size 128x128, and the bottom of the floater now says that size.
4. Click Cancel
5. Notice the bottom of the floater still says 128x128
6. Click the Save to Disk button
7. Notice the Width x Height says the size of your window while the bottom of the floater still says 128x128
8. Click Save
9. Looked at the image that was saved.

Observed: The saved image was 128x128 although requested size was larger.

Expected: The image size should have reset to the window's size after clicking Cancel in step 4. OR, maybe the image size should be reset when the Save to Disk button is clicked.
