shaderange - sets range of color indices

SPECIFICATION

C
shaderange(lowindex, highindex, z1, z2)
Colorindex lowindex, highindex;
Screencoord z1, z2;

FORTRAN
subroutine shader(lowindex, highindex, z1, z2)
integer*4 lowindex, highindex, z1, z2

Pascal
procedure shaderange(lowindex, highindex: Colorindex;
z1, z2: Screencoord);

DESCRIPTION

shaderange sets the range of color indices used in drawing depthcued lines and points. The range of values specified by z1, z2 is mapped linearly into the range of color indices used to draw lines and points.
