Description of the problem

As shown in the example below, FONT_LOGO can't change the size and color of the timestamp and label.

gmt basemap -R0/10/0/5 -JX5c/3c -Baf -UMylabel --FONT_LOGO=20p,Times-Bold,red -png map

Here are two issues:

1. I understand that the font size can't be changed because the size of the timestamp strings must match the height of the graphic "GMT" logo, but why can't the font color be changed?

2. The gmt.conf documentation says

   Font to use for text plotted as part of the GMT time logo [theme dependent]. Choose auto for automatic scaling with plot size."

   The description is inaccurate and misleading because the font size can't be scaled automatically.
