Problem Description:
	Synopsis : jpeg_compress is failed by Segmentation fault

	Fails on large files.

The following bugs were discovered internally. This patch fixes
them.

	1. Uses ICCCM compliant code to install a private color map
	2. The file load window now works consistently for a single
	   click and then click on the load button.
	3. When connected to the video server and vfctool is closed
	   to an icon it will stop the video server sending data.
	4. A new more efficient device driver has been included.
	   Instructions on installing it follow.

For use with OpenWindows V3.	

	1. Drag and drop works correctly with V3 clients.
	2. In a V3 environment performs extra checking to have 
	   VfcTool default to using shared memory for blits.
