			* There are two modes, and each mode interprets a tolerance value.

			* AVOID: In this mode, drawing is allowed only on destination pixels that

			* Tolerance near 0: avoid anything close to the op-color
			* Tolerance near 255: avoid only colors very close to the op-color
	*		*
	* @param opColor The color to avoid (or to target depending on Mode). Note		* TARGET: In this mode, drawing only occurs on destination pixels that
	* that the alpha in opColor is ignored.		* are similar to the op-color
	* @param tolerance How closely we compare a pixel to the opColor.		* Tolerance near 0: draw on colors that are very close to op-color
	* 0 - only operate if exact match		* Tolerance near 255: draw on colors that to the op-color
	* 255 - maximum gradation (blending) based on how
	* similar the pixel is to our opColor (max tolerance)
	* @param mode If we should avoid or target the opColor
