If you have a mask on the picture, you need to draw that mask in the new picture's mask if you want to keep it.
Modes:
| 0 | y = 0.33 * R + 0.5 * G + 0.16 * B | Faster version of 3 |
| 1 | y = 0.375 * R + 0.5 * G + 0.125 * B | Faster version of 3 |
| 2 | y = 0.2126 * R + 0.7152 * G + 0.0722 * B | Photometric/digital ITU-R |
| 3 | y = 0.299 * R + 0.587 * G + 0.114 * B | Digital CCIR601 |
Mode 2 and 3 uses doubles and mode 0 and 1 use integers so they should be faster.
Still Mode 0 and 1 are just approximation formulas which trade accuracy for perfomance.
GrayScaleMBS makes a copy of the picture while GrayScale2MBS edits in-place.
