Added support for using independent red, green and blue LUTs for certain scanners (e.g., D4000). Import of LUTs is supported through "Photoshop" curve format or using the settings file (scanLutR, scanLutG, scanLutB). If the "DONT_DISPLAY_RGB_LUTS" environment variable is not turned on, the LUTs will display in their respective colors if they are unique.

PLG Fix bug introduced 3.0-017 for the plugin license type.
FIL Added gamma resources for the following file types: TIFF, GIF, Targa, Postscript, JPEG, Frame, Interleaf,Sun Raster. Change default gamma for JPEG to 2.2.
SCA Made changes to the LUT that is saved and loaded so that it is of size (1<< scanner- >lutBits). Modified the Photoshop curve import to scale LUT to appropriate size. Interpolation is done for LUTs that are smaller in size than the scanner's supported LUT size.

Fixed in 3.0-017

OS Handle SunOS 4.1.2 and 4.1.1 case. They do not have 'cut'.
MIS First try to handle no PIXELFXDIR environment variable.
SCA Kludge to fix Settings Load for the plugin. Only pfx uses Xrm.c, so plugin cannot load D4000 settings properly.
SCA Many changes to fix problems associated with scanning at odd resolutions with the Horizon/Horizon Plus. Main problem was that GetWindow had to be called after the Scan command was issued.
SCA Changed quality_type from -1 (Preview quality) to 0 (Normal quality). Added Environment variable HORIZON_QUALITY to set this value.
SCA Support Y resolution up to 2540 ppi for grayscale and line art on Horizon +. Horizon + code does not support full resolution of the scanner for line art/grayscale.
