 * ibmcam_model2_320x240_parse_lines()
 *
 * This procedure deals with a weird RGB format that is produced by IBM
 * camera model 2 in modes 320x240 and above; 'x' below is 159 or 175,
 * depending on horizontal size of the picture:
 *
 * <--- 160 or 176 pairs of RA,RB bytes ----->
 * *-----------------------------------------* \
 * | RA0 | RB0 | RA1 | RB1 | ... | RAx | RBx |  \   This is pair of horizontal lines,
 * |-----+-----+-----+-----+ ... +-----+-----|   *- or one interlaced line, total
 * | B0  | G0  | B1  | G1  | ... | Bx  | Gx  |  /   120 or 144 such pairs which yield
 * |=====+=====+=====+=====+ ... +=====+=====| /    240 or 288 lines after deinterlacing.
 *
 * Each group of FOUR bytes (RAi, RBi, Bi, Gi) where i=0..frame_width/2-1
 * defines ONE pixel. Therefore this format yields 176x144 "decoded"
 * resolution at best. I do not know why camera sends such format - the
 * previous model (1) just used interlaced I420 and everyone was happy.
 *
 * I do not know what is the difference between RAi and RBi bytes. Both
 * seemingly represent R component, but slightly vary in value (so that
 * the picture looks a bit colored if one or another is used). I use
 * them both as R component in attempt to at least partially recover the
 * lost resolution.
