[GRASS-dev] Upon the mini color bars in r.colors' manual

GRASS GIS GRASS GIS developer

Hi!

I really like the mini color bars presented for each color table in the manual
of the "r.colors" module (sourced from <grass_trunk/dist.x86_64-unknown-linux-
gnu/docs/html>).

I'd like to propose, though, to remove the thick black borderline or, at
least, make it less black and thinner. All in all, make it less "dominant".

Thank you, Nikos

yeah, that's a side product of using the Cairo driver. If you look at
the versions in devbr6 they aren't like that:
https://trac.osgeo.org/grass/browser/grass/branches/develbranch_6/raster/r.colors/thumbnails

(d.colortable called using the PNG driver there)

and grey.log, grey.eq and random thumbnails still need some work.

Indeed, they look smoother.
