/*
* GPGC - an opaque object, holding current drawing parameters.
*
* Return value 0 for set methods indicates success, any other is error.
*
* We use very primitive tagging here, but it is suitable for libgnomeprint:
* CTM, line, dash, color and font can be tagged as unset, clear or changed. It is
* convenient way for print context to mark, whether they need to specify
* style attributes for next serialized drawing call.
* GC can also include single data value, which is used by libgnomeprintui
* to store pointer to current GnomeCanvasGroup. It does not do any reference
* handling, so it can be used only if we really know, what we are doing.
