This looks slightly nicer on very pixel-dense screens (scale factors 5 and up) than nearest neighbour fractional upscaling does.
Also fix window icon disappearing at times and the window being resized after configuration changes.
We should maybe start preserving window size also at some point, the way we do position now.
Namely when the main window is resizeable and its size isn't the same as it would be with the active scale mode with resizing disabled.
Also fix window position not being restored when the main window is resizeable.
Another rat's nest; I'm still not entirely satisfied.
This introduces "frame personalities": one for embedded frames (emscripten), one for handheld devices and everything else that doesn't really work with windows (android), and one for everything else. For now these affect which frame options are configurable by the user and what values they are forced to take if they are not configurable, and whether optimal scale is guessed based on screen size.
Also introduce a future TouchUI config node to allow switching between normal and touch-optimized UI on android. Again, because chromebooks and other android devices with mouse and keyboard support are a thing.
Also enable debugging of debug builds of android. It took me hours to attach a stupid debugger to the process; see:

I also had to adb forward the port that lldb was supposedly talking to lldb-server over because otherwise it wouldn't attach; I don't get it either.
This is good enough for now but also more limited than I'd like because if the thumbnail arrives (gets rendered or downloaded) later than the preview is opened, it's never shown.
This also fixes local save thumbnails being resized such that they are just short of filling the space they are supposed to.
Also fix textboxes drawing their borders in the wrong place.
A bug existed before where certain events would not update Engine's lastTick. If the sim was lagging hard, then this could cause "script is not responding" errors to appear in unintentional situations.
The starting execution time is tracked in LuaScriptInterface instead now, and set in tpt_lua_pcall
Request ownership is no longer flaky. Requests are now owned by the code that makes requests, and Requests and the RequestManager co-own RequestHandles. RequestManager disowns a RequestHandle if it's done with it or if Request code reports that it's no longer needed.
All libcurl code has been moved to RequestManager. This is nice because once NOHTTP is removed, we can add any number of RequestManager implementations, for example one for Android.
Client outliving RequestManager is still a problem, this will have to be addressed later.
