The arguments for fillcolor and linecolor can be any named X11 color (as found in grass5/etc/rgb.txt), a hexidecimal color string (like "AFDF00"), or an RGB triplet specified as "rgb(red green blue)". Hexidecimal color strings must be six characters where each pair represents the red, green and blue colors, respectively. RGB values must be between 0 and 255 for each component. Do not use any separator besides a space between the RGB numbers.
The user can optionally choose to restrict drawing operations to selected polygons by specifying one or more area category numbers using the catnum argument.
The routine for handling holes in polygons is relatively slow. Therefore, large maps containing a large number of holes will suffer a significant performance penalty.
It is the intention of GRASS developers to create a better mechanism for persistent storage of vector drawing instructions in the future.
There is a slight disagreement between the output of d.vect and d.area regarding the map coordinate to screen coordinate conversion. This leads to undesirable results when both are used.
