/** FILE: cursors.c ********** Module Header ********************************
*
* Control panel applet for Cursors configuration. This file holds
* everything to do with the "Cursors" dialog box in the Control Panel.
*
* If this applet gets incorporated into the MAIN.CPL module, look
* for the define NOTINMAIN below. This marks some code that will
* need to be modified.
*
* History:
* 12:30 on Tues 23 Apr 1991 -by- Steve Cathcart [stevecat]
* Took base code from Win 3.1 source
* 12-22-91 DarrinM Created from MOUSE.C
* 07-31-92 DarrinM Revived.
* 01-04-93 ByronD Cleaned up, etc.
* 03-25-93 JonPa Changed .ANI file format from RAD to RIFF
* 04-29-93 JonPa Pull strings out of resource file
* 05-20-93 ErikGav Added schemes
