Tcl/Tk projects

Ports of AndroWish and undroidwish (Tcl/Tk on SDL2, with the full AndroWish extension set) to targets the upstream project does not build for: iOS/iPadOS, arm64 macOS, Tcl/Tk 9.1 on Android, and the browser. Plus the supporting libraries used to run the Decent Espresso tablet app on those targets — Bluetooth LE for macOS and Linux, an OAuth 2.0 client, and a BLT graph-redraw patch.
