I am trying to generate a cursor (of the X-10 type) that will behave the same
on monochrome screens.  I use XCreateBitmapFromData and XCreatePixmapCursor.
I want it to have WHITE foreground. The problem is as follows: no matter what 
is the value that I select for the foreground or background I get a WHITE
cursor on an IBM AED (experimental display) and a BLACK cursor on an IBM 
apa16 display.  Since I use a "black" window, the cursor is totally invisible
with the apa16.

I noticed that the "X-cross" cursor is white with black border on the AED and
black with white border on the apa16 and other color displays.  How can I
get my cursor to come up WHITE instead of BLACK?  Any help is appreciated.

The code follows.

DefineCursor()
{


	int x, y;
	Pixmap bm;
	Pixmap bm2;
	XColor color;
	unsigned short curs[16];

	/* ...... */

	/* set color: I want WHITE */
	color.pixel = WhitePixel(display, DefaultScreen(display));
	XQueryColor(display,
		DefaultColormap(display, DefaultScreen(display)),
		&color);

	bm = XCreateBitmapFromData(display, DefaultRootWindow(display),
		curs, 16, 16);
	bm2 = XCreateBitmapFromData(display, DefaultRootWindow(display),
		curs, 16, 16);
	cur = XCreatePixmapCursor(display, bm, bm2,
	    &color, &color,
	    x,
	    y ));
	XFreePixmap(display, bm2);
	XFreePixmap(display, bm);
}
