New environment variables: AFNI_1DPLOT_COLOR_xx

This variable lets you set the colors used in the 1dplot program (and other similar graphs). Here, "xx" is a number from "01" to "19". The value of the environment variable must be in the form "rgbi:rf/gf/bf", where each color intensity (rf, gf, bf) is a number between 0.0 and 1.0. For example, "rgbi:1.0/1.0/0.0" is yellow. By default, the first 4 colors are defined as the equivalents of

setenv AFNI_1DPLOT_COLOR_01 rgbi:0.0/0.0/0.0 == BLACK
setenv AFNI_1DPLOT_COLOR_02 rgbi:0.9/0.0/0.0 == RED
setenv AFNI_1DPLOT_COLOR_03 rgbi:0.0/0.7/0.0 == GREEN
setenv AFNI_1DPLOT_COLOR_04 rgbi:0.0/0.0/0.9 == BLUE

You can alter these colors. The largest color number you define will be the last color index used; if more line colors are needed, they will cycle back to color 01. If you leave a gap (e.g., you define color 06 but not 05), then the undefined colors are black.

You can't use other X11 ways of specifying colors, since 1dplot might be run without using X11 (i.e., with the "-ps" option).
