o3djs: Make bump shader code compile for webgl.

o3djs: Make bump shader code compile for webgl.

BUG=none
TEST=collada mesh with bumpUV enabled and using the lambert shader.

Committed: http://src.chromium.org/viewvc/chrome?view=rev&revision=55001

The collada mesh here uses bump/normal maps:
http://inst.eecs.berkeley.edu/~pathorn/skinned_robot.zip

A lot of the changes were things like adding varying_ prefixes. Note that this
mesh still doesn't look right despite all the texture files being power-of-two
and show up in the devtools resources.

Do I need to convert the .zip to o3dtgz->json in order to load the model?

The zip contains the original .dae, the converted scene.json, and all the
images. Extract into samples/simpleviewer/assets and rename to "cube". Then open
up o3d-webgl-samples/simpleviewer/simpleviewer.html.

Note that you'll have to apply CL 3029050 for it to fully load.

When I unzip the file I only see the .dae and four .tga. No scene.json. Efforts
to convert it on my own result is 'Failed to load bitmap file
"MANTEXTURE-spec.tga"
Failed to load bitmap file "MANTEXTURE.tga"...'. Am I missing something?

Try again--I had uploaded the original by accident.

Fixed a mistake in the cg shader because I changed the output semantic names. I
did a comparison of the output programs before and after, and they are the same,
so I'm still going to commit.

However, my test mesh won't load in the o3d plugin before or after my change,
but because it has no TANGENT stream. Do you know of any scenes which use
bumpUV? The teapot doesn't seem to.
