Title: maketx.cpp modified to filter in linear colorspace

I've added a new flag --colorspace, which should be used when no color conversion is taking place. This makes it a bit more obvious that we're not changing the colorspace but merely defining the input colorspace for conversion to linear. Otherwise, we'd have to issue '--colorconvert sRGB sRGB' to get the same effect and that's a little too implicit to get what we're after.
