- fixed a secondary error when dropping non-list, non-downloader pngs on Lain's easy downloader import window, and fixed a 'no interesting objects' reporting test when dropping multiple pngs
- added a 'cache report mode' to help debug image and thumb caching issues
- refactored the media viewer code to a new 'canvas' submodule
- improved the error reporting when a thumbnail cannot be generated for a file being imported
- fixed an error in zoom center calculation when a change zoom event was sent in the split-second during media viewer initialisation
- I think I fixed an issue where pages could sometimes not automatically move on from 'loading initial files' statusbar text when initialising the session
- the requirements.txt now specifies 'requests' 2.23.0 exactly, as newer versions seemed to be giving odd urllib3 attribute binding errors (seems maybe a session thread safety thing) when recovering from connection failures. this should update the macOS build as well as anyone running from source who wants to re-run the requirements.txt. I hacked in a catch for this error case anyway, just a manual retry like a normal connection error, we'll see how it goes (issue #665)
- patched an unusual file import bug for a flash file with an inverted bounding box that resulted in negative reported resolution. flash now takes absolute values for width and height

next week

Back to multiple local file services. Mostly more backend cleanup and prepping File Import Options and the Client API for talking to multiple locations.
