/* target_depth :: pixel bit depth of target map */
/* x_offset :: horizontal offset of source in target */
/* y_offset :: vertical offset of source in target */
/* color :: color to use when blitting to color pixmap */

/* <Note> */
/* an error occurs when the target bit depth isn't supported, or */
/* if the source's bit depth isn't 1. */
/* */
/* the offsets are relative to the top-left corner of the target */
/* map. Positive y are downwards. */
