tessellated read in, texture, and another test page

The tessellated data can be read in, buffers are created for texture and
vertices, and type. Then rendered. test.html opens a tessellated file.
test2.html opens our fake polygon. Both are texture mapped. More scripts
added, with TessGET reading in a poly3GL file.
