[Seaside] [ENH] WAForm to prevent degradation of rendered images

[Brent Pinkney]

Hi,

Please confirm that you have loaded both the mimeTypesFor-brp.1 and  
waForm-brp.2 changesets.

Can you put a 'self halt.' in WAForm>>asMIMEDocument and reload you page  
with a new session.

Please confirm that

	a) the method halts in WAForm (not Form)
	b) the contentType is 'image/png'
	c) the depth is correct (> 8)
	d) the correct readerClass is answered

Thanks

Brent
