A small addition to allow importing the gamma table from a VCGT (Video Card Gamma Table) file. This is a simple text file with 256 lines, each line with four integer values (separated by spaces): row number, red value, green value and blue value. The RGB values are 16bit wide; the import process converts these to 10bit as required by the JVC projector.

This file is one of the available export formats of LightSpace by Light Illusion. There might by other applications that produce this output format. AFAIK, it its normally used when calibrating computer video cards.

Uploading a LightSpace VCGT file to the projector allows for a 256 step grayscale calibration.
