[PATCH] Really turn textures off when `-t' is passed

[Ludovic Courtès]

Hi,

Currently, `-t' has approximately no effect on the PostScript output.
This is because PS code for textures still gets output by
address@hidden' (in `coltex') and installed through an invocation of
the `LoutSetTexture' PS function.

The patch makes `LoutSetTexture' a no-op when `UseTexture' is false,
which guarantees that the PS interpreter never gets to install any
textures.

Thanks,
Ludovic.
