[X3D-Public] X3D MultiTexture tests

[Michalis Kamburelis]

Hi,

As promised, I created a number of test files to check X3D 
multi-texturing support in various browsers. You can download them (as 
zip, or one-by-one, or from SVN) from this page:

   http://castle-engine.sourceforge.net/x3d_multi_texturing.php

There's also a description and reference screenshot for each test. I 
also moved to that page the description of all problems/my proposed 
solutions related to X3D multi-texturing (and also one issue that 
actually concerns single-texturing but is related to multi-texturing, 
see the bottom).

Most of these examples are cleaned, extended (and with much more 
comments) tests from view3dscene(Castle Game Engine) demo_models. They 
were cleaned to not use various vie3dscene(Castle Game Engine) specific 
extensions.

I will be working on these tests more this week. Primary task is now to 
gather how well other X3D browsers handle them. Right now I simply 
tested them with view3dscene and FreeWRL (the latter doesn't seem to 
support much besides basic multi-texturing; all 
MultiTexture.mode/source/function values seem ignored).

I'm sure I will also find more ideas to extend/improve these tests.

Comments are of course welcome. Especially:
1. How other X3D browser implementors feel about the problems and 
proposed solutions on that page. Would you be in favor of applying such 
clarifications to X3D multi-texturing specification (texturing 
component)? Or would you prefer different clarifications?
2. How do other browsers behave on these test files.

Michalis
