The larger the display not only the more pixela that need to be drawn

but there are more to be calculated.


The important optimizing tip is to reduce the amount of screen that

needs to be redrawn. Draw a box around everything in an image that

changes and that is what will have to be redrawn. By reducing the

redrawing area you will likely speed the animation.


For instance if you have the main change of the animation in the lower

right and have a star in the upper left that fades in and out by just

changing that star from fading start to blinking on two frames off 4

frames while the animation in the bottom right plays this will reduce

the screen draw from including the star 50% of the time. Stopping it

from blinking at all will remove it from the screen draw area for all 6

frames. 


Doing one thing at a time and reducing the amount of screen area

involved at any one time will reduce the processing needs and time to

redraw the screen and thus allow faster animation speed.
