Description

This function reads the hardware color palette information from the hardware, and is only valid in 8-bpp and lower color index modes. Color palette information is returns from this function in an array of GA_paletteExt structures. Each value in the GA_paletteExt structure is 16-bits wide, with a range of 0 to 65535.  Note that this is different to the regular SetPaletteData function, which takes 8-bit wide values. Internally the driver will convert the 16-bit palette values to 8-bits if this is what the underlying hardware supports.
