|    Hi.  If you've been using the X window dump to imagen laser program

|    behavior on the Imagen when it prints the right edge of the window
|    dump.  This apparently happens if the dump isn't a multiple of
|    32-bits wide.  The Imagen processor likes bitmaps to be in "patches"
|    which are 32-bits wide and tends to pad with a strange pattern when
|    given bitmaps which are otherwise legitimate.

|    The solution of course is to make your window dumps an integral
|    multiple of 32-bits wide.  The way to do that is to resize the
|    window prior to dumping it, generating an ExposeWindow event so the

Actually in a version of xipr (with a different ancestry) that I
modified, I made xipr copy the window image to a different buffer,
padding to a longword boundary in both directions with zero bits. More
transparent to the user that way.
