D1227: Print Rasterization Event

This message is emitted from Direct2D print. It indicates that one of the following operations caused a need for rasterization:

• Use of a D2D1_LAYER_OPTIONS1_INITIALIZE_FROM_BACKGROUND layer.
• Use of the primitive blend mode SOURCE COPY, or any blend mode other than SOURCE OVER.
• Use of certain composite modes such as BOUNDED_SOURCE_COPY, DESTINATION_OUT, SOURCE_ATOP, XOR, PLUS, or INVERT.
• Use of DrawGdiMetafile.
• Use of a 4x4 (or, perspective) transformation in a DrawBitmap call.

For optimal performance, these operations should be avoided if possible.
