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.
don't recreate window every scale / fullscreen change
better renderer handling, input scaling no longer needed even if window resizing is enabled
load/save window position (replaces old windows code to do this)
calculate initial mouse position on startup because sdl no longer does this for us
mouse movement captured outside the window when mouse is down
fullscreen now focuses the window (there is a bug where you have to click once to get mouse input, though)
add linux icon, will need to be redone properly because it's offcentered with a black border (mask isn't present)
allow typing ~ into the console + some other fixes
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)
