Also clear SaveRenderer graphics cache along with the main Renderer's when needed, and revert to built-in element callbacks rather than nothing at all when assigning nil to a callback slot in Lua.
event.register(event.mousedown, function(...) print(...) end)
event.unregister(event.mousedown, somefunc)
mouseclick event split into mousedown, mouseup, mousemove, mousewheel
keypress event split into keypress, keyrelease, textinput. key* events only contain keycode and scancode, don't attempt to represent a letter (was very broken at this before). Also have helpful shift/ctrl/alt flags passed in. textinput just represents inserted text, can probably even handle foreign characters.
register_step replaced with event.tick event
All legacy register_* and unregister_ functions are removed. There is a compatibility lua script, might embed it later. tpt.set_shortcuts / tpt.test also removed. event.getmodifiers added, just a misc function to get the currently held modifiers
Lots of code duplication to handle each event is removed, it's not handled in a more generic way. Although the Event class / child classes could use some work.
Still currently in process, there are some issues:
Windows version doesn't work, mac version might not work, opengl might not work
Icon doesn't work (on Linux at least)
Lua will need some changes, there are some sdl 1.2 hacks in there
When entering fullscreen, the window loses focus
When holding down mouse out of bounds, mouse move events stop being sent
When letting go of mouse out of bounds, mouseup event doesn't take into account double scale mode
Clicking on startup without moving mouse will draw at 0,0 for a frame
Renderer probably won't compile because USE_SDL doesn't entirely work
... and maybe others
Some nice things were done though:
no more blit2, sdl can do the scaling itself
3d effect removed, no reason to support this joke any longer
No need to support copy/paste ourselves, sdl does it now
text handling done much better now, separate events for key presses and text input
when a new window is shown, all events ignored until next tick (ignore textinput event if window shown from key press event like console)
remove 'r' record shortcut
add tpt.record function. Still gives the user a confirm prompt
recordings now go into recordings/<timestamp>/, where timestamp is the time the recording was started. <timestamp> is returned by the tpt.record function. Each new recording starts the filenames over at 0 again.
you probably still need a lua script to use the recording feature, this should make it easier for those
you can get current OS / build information, exe name, restart tpt, open a link in the web browser, and use clipboard copy/paste functions
Also remove some older Platform.h file which wasn't really needed or used
