Change History (most recent first):
<11> 8/26/92 DTY Roll in latest changes for A/UX.
<10> 4/9/92 KST #1025131,<JH>: Changing SWM from a background app to a driver.
Adding a new call: SendEventToSWMDriver.
<9> 10/15/91 YK Added GetFrontAppFloatLayer macro.
<8> 10/9/91 YK Added FindAppFloatLayer. Searches IMLayer for the application
layer.
<7> 1/28/91 DFH JSM,#81425:Remove EnableSwitching and DisableSwitching calls.
They are now in MFPrivate.h.
<6> 1/14/91 DFH (JDR) Conditionalize out AUX support.
<4> 12/10/90 DFH Moved file attribute and Finder flag equates to SysMisc.h.
<3> 12/5/90 DFH Added #defines for prettier access to AuxDispatch.
<2> 11/27/90 DFH Removed unneeded parameter from cpu_resched.
<0> x/xx/86 PYG New Today.
