Allow mouse scrolling while annotating

[Svk1190]

It can be helpful to scroll the document while it is being annotated. For example, we can take a note (annotation by Livedraw) from page 1 of the document, and then scroll to page 5, and then again take some annotation. Currently, we need to release the control after page 1, scroll to the desired page, and then recover control of Livedraw at page 5.

So it would be helpful if we can scroll an underlying document by mouse without needing to release control of Livedraw. This would mean that the mouse would no longer be available for changing the brush size, and the brush size can only be changed by clicking the brush icon or by the arrow buttons. Since changing the brush size is a one-time thing, maybe sacrificing the mouse control for brush size might not be bad, while leaving the mouse for document control.

It would be useful. For now, I created a script that simulates mouse clicks on Clear screen, then clicks on Release/Recover, then moves to the slide and uses the scroll wheel. I used program called "Macro Recorder" for that: https://www.macrorecorder.com

Using shortcuts + and - is enough to change the pointer size.
I think the app should not change the mouse scroll feature.
