Yes, this is the right file!

I'm not really sure about some problems with the input LUT's. The pcdig
has 2 16x16bit LUT's. Till now I only use the lower one, because we don't
have cameras with more than 16bit.
Also the PIXEL_SIZE=24 entry in the config file will not work. My
suggestion is to set PIXEL_SIZE=16, so the lower LUT is filled in a linear
manner (that is what you need). Later use the HIOC_PCD_SET_LUT1 to load a
self defined mapping into the upper LUT. To do this, define a union
pcd_lut_t, fill it with linearized values (0->0 .... 65535->65535), and
call the ioctl with the union pointer as argument. There are also some
PCD_GET_LUT0|1 calls to verify the loaded mappings.

...But not really much of this calls are tested...

The bytes should lay in the memory like

	RGBRGBRGBRGBRGBRGB

am I right?
