[X3D-Public] PixelTexture render problems in major browsers

There is a problem with PixelTexture rendering in most of the major browsers.
Of five tested, only Xj3D and FreeWrl seem to get this simple example correct.

<PixelTexture image='2 2 3 0xFF0000 0xFFFF00 0xFFFF00 0xFF0000'/>

which means
	pixel width  2
	pixel height 2
	color depth  3 (RGB values)

as shown in

would have the PixelTexture produce an image file like the first one
attached: RedYellowCheckerboard.png

However BS Contact, Instant Reality and Octaga all produce a scene
looking like the second snapshot: PixelTextureFlawedRendering.png

This is such a simple PixelTexture that it appears clearly to be a
flaw in each browser.  Possibly it is an unreported deficiency or
lack of clarity in the X3D Specification, however.

Can each of the browser companies address this issue please?  TIA.

all the best, Don
