// Raster palette 
// The requirement for the ulValidPalID entry can be explained by an

// 1,4,8bpp images are downloaded using palettes (BGetPalette in palette.cpp). 
// We create a different palette for each bpp image (look at ECIDPalette above).
// A palette for 4bpp image has 16 colors while that for 8bpp has 256 colors. 
// Suppose a 4bpp image is followed by 8bpp image. When palette for 4bpp image
// is being downloaded  eRASTER_CID_4BIT_PALETTE is the active palette.
// When palette for 8bpp image is downloaded eRASTER_CID_8BIT_PALETTE is the
// active palette. Can the palette entries downloaded in 4bpp case be re-used
// in 8bpp case.(i.e. after downloading 16 colors in first case, can we download 
// only 256-16 colors in second case).
// Answer is NO, cos the palette ID's in both are cases are different. 
// Colors from one palette id cannot be carried over to colors to a different
// palette ID. So we use the ulValidPalID to record which color has been downloaded
// for which palette.
// if ulValidPalID[0] = 1, it means that color is downloaded for eRASTER_CID_1BIT_PALETTE
// if ulValidPalID[0] = 4, it means that color is downloaded for eRASTER_CID_4BIT_PALETTE
