36 * "type" is the type of visual this is (PseudoColor, TrueColor, etc).
37 * "depth" is the bit depth of this visual.
38 * "colormap_size" is the size of a colormap for this visual.
39 * "bits_per_rgb" is the number of significant bits per red, green and blue.
40 * The red, green and blue masks, shifts and precisions refer
41 * to value needed to calculate pixel values in TrueColor and DirectColor
42 * visuals. The "mask" is the significant bits within the pixel. The
43 * "shift" is the number of bits left we must shift a primary for it
44 * to be in position (according to the "mask"). "prec" refers to how
45 * much precision the pixel value contains for a particular primary.
