This program requires MPW 2.0.2 and MacApp 1.1.1 to build.

This is the Òcommercial qualityÓ version of FracApp.  This version 
handles multiple documents, and it supports color table animation 
using an off-screen gDevice with a port.  The updates to the 
screen using _CopyBits are as fast as possible.  FracApp does not 
use the Palette Manager, except to provide for the system palette, 
or color modes with less than 255 colors.  For the color table 
animation, it uses the Color Manager and handles the colors 
itself.  Strict compatibility was relaxed to allow for a higher 
performance program.  This is the most ÒrealÓ of the FracApp 
programs.

As color on the Macintosh evolves, we hope that future versions of 
this program will be able to use the Palette Manager and maintain 
the level of performance.  To achieve this, we will have to attain 
better QuickDraw (i.e., _CopyBits) and Palette Manager 
integration.
