A new field background pattern, FP_BITMAPCLEAR, is introduced for the CellAttribute, FormField, FrameExec, and FrameSource classes. FP_BITMAPCLEAR is also introduced as a new foreground pattern for the BarField and CellAttribute classes.

A transparent bitmap image can be assigned to a class's FgBitmap or BgBitmap attribute. This image can be specified as a transparent background or foreground image by setting the class's BgPattern or FgPattern attribute respectively to FP_BITMAPCLEAR.

A field with its BgPattern or FgPattern attribute set to FP_BITMAPCLEAR first paints the field's background or foreground as if it were set to FP_CLEAR. If the field has a bitmap image assigned in BgBitmap or FgBitmap, the bitmap is then painted. If the bitmap contains transparent pixels, whatever is underneath them will show through.

Although the BgPattern attribute is defined for all child classes of FormField, it is not available for MenuFields.
