Genaral graphic routines for text and pictures

Hi

I have had an old flip type display on the shelf for many years, and now a took some time to write an interface for it.
Running on my Xduino board with an Xmega plus several sensors and an RTC chip with battery backup.

My driver essentially support one single operation, which is setting and resetting a single dot (pixel)
So fas so good, and of course I could continue writing code for displaying text, numbers, or even simple graphics like squares, circles and lines,
But lazy as I am I started wondering if noone already have written such an engine?

I mean, the only thing that really is different from display to display is the mechanism of setting a pixel at a certain coordinate.
Yes, I realize that writing text by setting one pixel at a time is not very efficient. But disregard that for a moment.
The simplicity is tempting. Provide a driver for setting/resetting a pixel in the display, and the rest is standard. Nice!

Could it be that somewhere a forum member already have done just this. Written a graphic routine where the only requirement is a dedicated driver able to write one pixel.

Merry Christmas
