D2607: Switch eye dropper to use linear color space internally

Browse Source 
This switches the internal color representation of the eye dropper from display space to linear. Any time a linear color is requested and the color is picked from a linear object, the result is now precise to the bit as the color gets patched through directly. Color space conversion now only happens when a color is picked from non-linear display space objects or when the color is requested to be returned in non-linear space.

In addition, this patch changes the DifferenceMatte node to interpret a tolerance of 0.0 to accept colors that are identical bit by bit, as apposed to simply refusing all colors.
