+// Helper function definitions for UNO API fallbacks to replace SvxBrushItem. The
+// idea is to have fallbacks to create a SvxBrushItem if needed for backwards compatibility
+// if needed from the SfxItemSet and vice versa. This is used in cases where e.g. UNO API
+// accesses to slots in the SvxBrushItem are used (see cases in SvxBrushItem::QueryValue
+// and SvxBrushItem::PutValue as MID_BACK_COLOR and similar).
+// To make this work, a cycle of creating a SvxBrushItem from a SfxItemSet, changing a value
+// using PutValue, putting back to the SfxItemSet should create the *same* SvxBrushItem
+// the next time this will be created using getSvxBrushItemFromSourceSet. For more details,
+// see comments at the implementations of that two methods.
+
+// Set the equivalent in the range [XATTR_FILL_FIRST .. XATTR_FILL_LAST] in the given
+// SfxItemSet to create the same FillStyle as is expressed by the given SvxBrushItem.
+// This method will reset all items in the XATTR_FILL_* range first.

+// Create a SvxBrushItem as close as possible to the settings in the DrawingLayer
+// items in the range [XATTR_FILL_FIRST .. XATTR_FILL_LAST]. Since this is not 100%
+// representable this may lead to reduced data. With nBackgroundID a Which-ID for the
+// to-be-created SvxBrushItem has to be given (default should be 99 as in RES_BACKGROUND).
