-text editor functionality:
-
-keep text as 1 string? or as a vector of strings?
-prob faster to use a vector of strings for display
-makes it more awkward for selections? keep track of which line/char to start and end
-
-alternative - go through text and seperate into lines either by width or by /n every time it changes
-keep a display copy with /n's inserted?
alternative - just have a horizontal scroll bar (contextual)
maybe draw into an FBO in order to put a window in a window

vector insert a problem performance wise?
you need to use an iterator to insert into a vector anyway- may as well use a list
