link and build and run properly with rocket inited..time to load stuff
aaand it renders. though i had to disable a lot of my stuff..

i'd like to find or use a dfully gl3 renderer for it..or make my own
maybe.
push gui code into GUI class...SDL2 system interface now handles

input for the most part..
create a somewhat hacky settings class, but it's better than

a bunch of statics in Game class.

handle mouse presses for sdl2..and convert those integers
implement sdl2 mouse wheel rocket handling
showcase of event handling for librocket
make the titlebar div instead of span
center titlebar, change titlebar icon..make it span the whole width

remove titlebar icon for now, maybe we'll use that some other year.

now there's just a slight 2 or 3px offset on the titlebar to the right
that's really bugging me..
fix offset, rm icon for now
create options dialog, lot of removing junk files
make the mainmenu optionsdialg etc. inherit event listener.

having an additional class just for listening for events for each element
is pretty silly (and the tutorials do it that way too), and it just
involves the uses of statics and more pointers
initial handling of options dialog events
initial attempt to make a slider..
slider has images and works, the images aren't proper though of course

since i haven't made them yet..
add sound effect/music sliders. make slider tile horiz
replace the rocket sample gui image with our new one

make the titlebar and window use proper (mostly) tex coords
bind button normal hover pressed
make the buttons slightly less ridiculously huge
dropdown box normal and arrow
early radiobutton binding
size radio properly
