…m/win32 directory tree - Inno Setup: remove the tesseract data files from the setup: those are HUGE and update very infrequently so we better come up with a solution where we either download them or install them separately. #2

The purpose of a "snapshot" save is to allow us to dump the current state of a PDF document (including edits, but excluding undo/redo history) in such a way that the version in memory remains unchanged. There are a couple of use cases for this: 1) Load a form, fill in some fields, print it. In order to do the print, we need to save the document as a standard valid PDF to send to a remote print service. After printing, if we then edit the document some more and save it out, we only want to see 1 incremental section used, rather than 2 (i.e. the saving for printing should not cause the 'underlying' document to be updated). 2) When running as an app on a mobile device, when we are put into the background, we need to save our state so that if the app is killed and later restarted, we can pick up where we left off. Again this should not involved writing a new incremental section to the document. This commit solves for case #1. Case #2 will require this, plus both the ability to save undo/redo history, and the ability to 'reopen' the last incremental update.

Have the installer check if the latest tessdata is installed and if not, download the additional installer and run it?
Or provide a full installer and an 'updates only' installer a la Mega Codec Pack et al? 🤔
