Why did this need to change?

It's the bug I mentioned above. without this change,
GLRenderer::EnqueueTextureQuad() don't know texture size. It's ok so far,
because the method doesn't use texture size. However, now we need texture size
to calculate one unit texel.

The reason is that ResourceProvider::CreateResourceFromTextureMailbox() set size
to Resource using size in TextureMailbox.

I have a plan to fix it in next CL by replacing cc::TextureMailbox(3 params) to
cc::TextureMailbox(6 params) in all place.
