Sets the pixel under the turtle to the color described by
colorvector input must be a three item list of [red green blue] intensities, each of which must be an integer from 0 to 255.
For an explanation of color vectors see Using Color.
SETPIXEL is similar to running
SETPENSIZE 1 SETPENCOLOR colorvector PENPAINT FORWARD 0, except that SETPIXEL is faster and doesn't affect the pen state.
By using PIXEL and SETPIXEL, you can scan and redraw an image at a new orientation (for example, to rotate a bitmap).
SETPIXEL can be used in PERSPECTIVE mode but only the "closest" pixel set is seen.
Examples\3D\3DBITMAP.LGO for an example of using SETPIXEL in perspective mode.
PENUP SETXY -128 -128 FOR [red 0 255] [ FOR [green 0 255] [ SETPIXEL (LIST :red :green 0) FORWARD 1 ] BACK 256 RIGHT 90 FORWARD 1 LEFT 90 ]
