2.2.4.1.1.2.1 CLEARCODEC_BAND
The CLEARCODEC_BAND structure specifies a horizontal band that is composed of columns of pixels. Each of these columns is referred to as a "V-Bar". The maximum height of a band is 52 pixels.

xStart (2 bytes): A 16-bit unsigned integer that specifies the horizontal position (relative to the left edge of the bitmap) where the band starts.
xEnd (2 bytes): A 16-bit unsigned integer that specifies the horizontal position (relative to the left edge of the bitmap) where the band ends. This is an inclusive coordinate.
yStart (2 bytes): A 16-bit unsigned integer that specifies the vertical position (relative to the top edge of the bitmap) where the band starts.
yEnd (2 bytes): A 16-bit unsigned integer that specifies the vertical position (relative to the top edge of the bitmap) where the band ends. This is an inclusive coordinate.
blueBkg (1 byte): An 8-bit unsigned integer that specifies the blue value of the background for this band.
greenBkg (1 byte): An 8-bit unsigned integer that specifies the green value of the background for this band.
redBkg (1 byte): An 8-bit unsigned integer that specifies the red value of the background for this band.
vBars (variable): A variable-length array of CLEARCODEC_VBAR (section 2.2.4.1.1.2.1.1) structures. The total count of CLEARCODEC_VBAR structures MUST be equal to (xEnd - xStart + 1), one per x-coordinate in the band. The V-Bars are encoded from left to right, with the first V-Bar corresponding to the xStart field and the last corresponding to the xEnd field.
