a good start, that is how I imagine it would look like. The user has to have the capability to design the tile structure (how many rows and columns per tile), as the contents of slides can be very different. |

Investigating the display of tile coordinates as a possible tool for users to keep track of which parts of a big Image they are viewing (or have viewed before).
Functionality is similar to https://openlayers.org/en/latest/examples/canvas-tiles.html but I couldn't get that code to work since it complained about 'no projection' when I added a
Debuglayer in iviewer.So instead, similar effect was produced with a custom
tileLoadFunctionin a subclass of the OmeroImage layer (should use same tile coordinates etc).I was also trying to keep track of the tiles where
tileLoadFunction()has been called before, so that when we render a tile, we can show if it's been loaded beforecount: 1etc in the screenshot. However, it seems to not get called more than once for each tile.
