	NEW FILES:
	* app/scan_convert.c
	* app/scan_convert.h: common code from free_select.c and
	    bezier_select.c

	MODIFIED FILES:
	* app/disp_callbacks.c: Fix for bug #2517 - dragging colour swatch
	    to image with no layers causes segfault.  Something is
	    repainting empty images as white rather than chequerboard as
	    well, which still needs fixing.

	* app/free_select.c: move code out to scan_convert.c
	* app/free_select.h: use ScanConvertPoint not FreeSelectPoint
	* tools/pdbgen/pdb/tools.pdb: ScanConvertPoint again
	* app/tools_cmds.c: generated version of above.
