Draws to the framebuffer by calling a function that contains drawing instructions.
The parameter, callback, is a function with the drawing instructions for the framebuffer. For example, calling myBuffer.draw(myFunction) will call a function named myFunction() to draw to the framebuffer. Doing so has the same effect as the following:
myBuffer.begin();
myFunction();
myBuffer.end();
