- Since Brush/Pen and Region objects are sharable,,, we can just use

- Example Allocating:
-
- // Save Kernel Space Pointer
- (PBRUSH)->pBrushAttr = IntGdiAllocObjAttr(GDIObjType_BRUSH_TYPE);
-
- // Kernel Space to User Space Pointer
- (PGDI_TABLE_ENTRY)->UserData = pBrushAttr;

-
- Example Freeing:
-
- (PGDI_TABLE_ENTRY)->UserData = NULL; // Zero the user ptr.
- UserHeapFree((PBRUSH)->pBrushAttr); // Free from kernel ptr.
- (PBRUSH)->pBrushAttr = NULL;
-
- Notes:
- Testing with DC_ATTR works but has drawing difficulties.
- Base on observation, (Over looking the obvious) we need to supply heap delta
- to user space gdi. Now, with testing, looks all normal.
