[FR] Draw & Laser pointer capability

[rezatester94]

Describe your request

At Mozilla Pdf.js, we can draw, sketch on our PDF file, you can include this feature to your plugin. Sometimes we do not need to give annotation, but tips need to give light graffiti, by drawing or giving a sign to our ODF file, well with the presence of this feature it will definitely make the Obsidian-PDF-Plus better.

Secondly, the feature, laser pointer, in excalidraws they have a laser pointer feature, as if we draw on our pdf but whatever we draw immediately disappear a few seconds afterwards. Hopefully you can also include this feature

This feature will bring the PDF++ addon close to perfect for me.
