DrawRectFrame(windowPtr, rect, [color])

Draw a rectangle frame (not filled in) specified by the rect coords.
windowPtr is the window pointer returned from Screen (PsychToolbox)

rect is a 1x4 vector - [x0 y0 x1 y1]

color is a 1x3 color vector - [r g b] with color range from 0:255
if color is not specified, rect is drawn in white

The idea for this came from the Screen('FrameRect') function. However,
Screen would only draw from top-left to bottom-right. This didn't work
well on the Haploscope when your view is mirrored.
Draw our own using the Screen('DrawLine') functions.
