Describing the fields of the Canvas Properties Dialog

The user access the image dimensions in the Canvas Properties Dialog.

The 'Others' tab

Here some properties can simply be locked (such that they can't be changed) and linked (so that changes in one entry simultaneously change other entries as well).

The 'Image' tab

Obviously here the image dimensions can be set. There seem to be basically three groups of fields to edit:

The on-screen size(?)
The fields Width and Height tell synfigstudio how many pixels the image shall cover at a zoom level of 100%.
The physical size
The physical width and height should tell how big the image is on some physical media. That could be when printing out images on paper, or maybe even on transparencies or film. Not all file formats can save this on exporting/rendering images.
The mysterious Image Area
Given as two points (upper-left and lower-right corner) which also define the image span (Pythagoras: Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://api.formulasearchengine.com/v1/":): {\displaystyle \text{span}=\sqrt{\Delta x^2 + \Delta y^2}} ). The unit seems to be not pixels but units, which are at 60 pixels each.
