[X3D-Public] support for .bmp image format, and possibly SVG

Thanks for the helpful considerations.

To be precise, PNG and JPG image formats are required for an X3D player.

> 18.4.1 ImageTexture
> Browsers shall support the JPEG (see 2. [JPEG]) and PNG (see ISO/IEC 15948) image file formats. In addition, browsers may support other image formats (EXAMPLE  CGM, ISO/IEC 8632) that can be rendered into a 2D image. Support for the GIF format (see [GIF]) is also recommended (including transparency).

GIF is currently recommended, but will likely become required since it 
is so common and no longer encumbered.  That was the only reason it 
wasn't required in the first place.

So, the prior proposal was whether to make BMP a recommended format for 
X3D player support in the preceding specification section.

Also under consideration:  Scalable Vector Graphics (SVG) as a candidate 
ImageTexture format.  Feedback welcome.

p.s. there aren't any sudden moves happening here... X3D v3.4 will take 
some time to play out.  Meanwhile X3D players are always welcome to add 
support for any formats they wish.

all the best, Don
