Sets the cel engine control word.

### Synopsis

`Err SetCEControl (Item bitmapItem,int32 controlWord,int32 controlMask)`

### Description

This call sets the cel engine control word of the bitmap specified by the bitmapItem argument. After this call, the newly modified control word is used whenever the bitmap renders cels. The controlMask argument controls the bits of the bitmap's control word that are modified by a call to `SetCEControl()`.

### Arguments

bitmapItem
  Item number of a bitmap structure.

  Value of the new control word for the bitmap.

controlMask
  Bit mask that controls whether the corresponding bit in controlWord is transferred to the CEControl word. If the controlMask bit is set, the corresponding bit in controlWord is transferred to the CEControl word; if the controlMask bit is clear, the corresponding bit in controlWord is ignored.

### Return Value
