Dear All,

	I've add more wrapper functions for clipping regions.

	Please get the patch at
	http://hpc.ee.ntu.edu.tw/~murphy/diff.region2.gz

GR_REGION_ID    GrNewRegion(void);
void            GrDestroyRegion(GR_REGION_ID region);
void            GrUnionRectWithRegion(GR_REGION_ID region, MWRECT *rect);
void            GrUnionRegion(GR_REGION_ID dst_rgn, GR_REGION_ID src_rgn1,
                        GR_REGION_ID src_rgn2);
void            GrIntersectRegion(GR_REGION_ID dst_rgn, GR_REGION_ID src_rgn1,
                        GR_REGION_ID src_rgn2);
void            GrSubtractRegion(GR_REGION_ID dst_rgn, GR_REGION_ID src_rgn1,
                        GR_REGION_ID src_rgn2);
void            GrXorRegion(GR_REGION_ID dst_rgn, GR_REGION_ID src_rgn1,
                        GR_REGION_ID src_rgn2);
void            GrSetGCRegion(GR_GC_ID gc, GR_REGION_ID region);
MWBOOL          GrPointInRegion(GR_REGION_ID region, MWCOORD x, MWCOORD y);
MWBOOL          GrRectInRegion(GR_REGION_ID region, MWRECT *rect);

	Test programs needed. :)

With regards,
Murphy

Super.  I'll add this ASAP to Nano-X.  BTW, the MWBOOL
and MWCOORDs will change to GR_BOOL and GR_COORD...

Regards,

Greg
