Thanks for suggestion, I will look into it.

Color blindness simulation for three types of anomalous trichromacy (protanomaly, deuteranomaly and tritanomaly) has been implemented.

To enable it, you should:

1. Clicking on 'Edit->Edit Transformatios...' menu item.
2. In the 'Transformations' dialog enable 'Enabled' check box.
3. Add 'Color vision deficiency' transformation to the list by clicking "Add" button.
4. Double click on the added transformation to edit its properties.
5. Click OK.

Other defect types will be implemented soon. Configuration interface is still work in progress.

I've written a Quantization transformer; it's attached here for consideration.

Basically, it allows you to determine what colors look like when matched to the nearest color in a quantized RGB colorcube, such as:

• GBA: 32 possible intensities of RGB
• SNES: 32 possible intensities, with white being clipped (darkest intensity = 0/32, highest intensity == 31/32), suitable for CRT TV display.
• Amiga: 16 possible intensities
• CPC: 3 possible intensities
• etc.. (EGA64, SMS, Genesis, MCGA,)

etc. It is useful for various game-developing purposes.

I'm happy with the quality of the code, personally; I only wonder whether 'clip top-end' is a clear enough description of the clipping option for the user to understand.

There was a couple of issues (both fixed in attached patch):

• "Clip top-end" check box state was not restored in configuration constructor.
• "Value" range included values 0 and 1 which could cause division by zero in apply() method.

'Clip top-end' is ok.

Other than that, it is ready to be committed.

Thanks :) I see I need to review whitespace more carefully. I'll commit your updated version after I add some other minor updates.
