allow save screenshot for non integer scales
This feature request is an extention of #21109 (closed). #21109 (closed) has the details to test saving screenshots. As mentioned at the bottom of #21109 (closed), we wish to allow users to scale screenshots to scale to non integer values. For instance, we want to save screenshots with a scale of 0.75 or 1.5. Then, text used for the color legend and simultaniously sources/ text should scale to this value, and also scale the same.
Again, see #21109 (closed) for details how to replicate this issue.
