The Rotate function schedules a rotate/mirror operation on a bitmap supplied in the srcBitmap and 

produces the output in the tgtBitmap.

The CBitmapRotatorBody is an active object and as such provides asynchronous operations

Preconditions:

aRequestStatus is not a NULL pointer

aSrcBitmap     is a fully constructed bitmap of unknown size including zero dimension

aTgtBitmap     is a fully constructed bitmap of unknown size including zero dimension

aAngle         is a member of the enumeration TRotationAngle 

Sucess Guarantee:

aTgtBitmap      contains the rotated bitmap

aRequestStatus  points to the value KErrNone

Minimal Guarantee:

The bitmap supplied in aSrcBitmap is unaltered

@param "TRequestStatus* aRequestStatus"

       a pointer to the completion status of the asynchronous operation.

@param "CFbsBitmap& aSrcBitmap"

       This bitmap should have been created

@param "CFbsBitmap& aTgtBitmap"

       This bitmap should have been created

@param "TRotationAngle aAngle" 

       is a member of the enumeration TRotationAngle and specifies the rotation mirror operation

@panic This function panics with TBitmapTransformsMain::ENoSourceBitmap when the aSrcBitmap has not been constructed

       i.e. its handle is zero
