Trixel.setDot(x, y, color)

x: dot horizontal position, 0 = leftmost
y: dot vertical position, 0 = topmost
color (optional): 0 = white, 1 = black
operator (optional): Boolean binary operator to combine old and new color values:
| new color | 1 | 1 | 0 | 0 | |
|---|---|---|---|---|---|
| old color | 1 | 0 | 1 | 0 | |
| boole_clr | 0 | 0 | 0 | 0 | ignore both colors, use white |
| boole_nor | 0 | 0 | 0 | 1 | |
| boole_andc2 | 0 | 0 | 1 | 0 | like white ink |
| boole_c2 | 0 | 0 | 1 | 1 | |
| boole_andc1 | 0 | 1 | 0 | 0 | |
| boole_c1 | 0 | 1 | 0 | 1 | |
| boole_xor | 0 | 1 | 1 | 0 | exclusive or: like negative ink — repeat to undo |
| boole_nand | 0 | 1 | 1 | 1 | |
| boole_and | 1 | 0 | 0 | 0 | |
| boole_eqv | 1 | 0 | 0 | 1 | |
| boole_1 | 1 | 0 | 1 | 0 | do nothing: ignore new color, use old color |
