textborder - Higher contrast text using a 1-pixel-thick border

This function draws text on a figure with a 1-pixel-thick border, which may be useful when simple text would be hard to read due to low contrast.

TEXTBORDER(X, Y, STRING)
Creates text on the current figure with a one-pixel border around it. The default colors are white text on a black border, which provides high contrast in most situations.

TEXTBORDER(X, Y, STRING, TEXT_COLOR, BORDER_COLOR)
Optional TEXT_COLOR and BORDER_COLOR specify the colors to be used.

Optional properties for the native TEXT function (such as 'FontSize') can be supplied after all the other parameters.
Since usually the units of the parent axes are not pixels, resizing it may subtly change the border of the text out of position. Either set the right size for the figure before calling TEXTBORDER, or always redraw the figure after resizing it.
