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
method to retreive text as a single string with \n's
special key functions including ENTER, BACKSPACE, DELETE, ARROW KEYS
drawing functionality: make line breaks (easier with mono font)
set box size - draw scrollbar & set scrollpoint - drag to scroll
insertion point/ selection - set with mouse -
get and set clipboard (ofxFensterManager.h)
vector insert a problem performance wise?
you need to use an iterator to insert into a vector anyway- may as well use a list

/*
not trivial if we deal with 1 string with /ns in
we have to scan the file for /ns every time we display the blinking cursor
is easier with vectors?
the difficulty here is that its messy to remember row/column
can we even get the height of a string formatted block
shorter strings make inserting quicker
could have a single string and maintain a vector representing line breaks- however inserting a char meansn having to manipulate the entire vector
with a vector of strings and then row/column insertion point its prob better
