Note that:

• Only attributes whose flags are set in flAttrsMask are modified.

• Attributes whose flags are set in both flDefsMask and flAttrsMask are set to their default values.

• Attributes whose flags are set only in flDefsMask, or whose flags are not set either in flDefsMask or flAttrsMask, are unchanged.

• Attributes whose flags are set only in flAttrsMask are set to the value specified by pAttrs.

When GreSetAttributes occurs within a path bracket, it must not be used to set the geometric line width for line attributes, nor used to set the foreground and background colors and mixes for character and marker attributes.
