+ − 1429 It might be nice if there was some way to tag the
+ − 1430 colors in the XPM file with whether they are the
+ − 1431 foreground - perhaps with logical color names somehow?
+ − 1432
+ − 1433 Once we have decided which color is the foreground, we
+ − 1434 need to ensure that that color corresponds to a `1' bit
+ − 1435 in the Pixmap. The XPM library wrote into the (1-bit)
+ − 1436 pixmap with XPutPixel, which will ignore all but the
+ − 1437 least significant bit.
+ − 1438
+ − 1439 This means that a 1 bit in the image corresponds to
+ − 1440 `fg' only if `fg.pixel' is odd.
+ − 1441
+ − 1442 (This also means that the image will be all the same
+ − 1443 color if both `fg' and `bg' are odd or even, but we can
+ − 1444 safely assume that that won't happen if the XPM file is
+ − 1445 sensible I think.)
+ − 1446
+ − 1447 The desired result is that the image use `1' to
+ − 1448 represent the foreground color, and `0' to represent
+ − 1449 the background color. So, we may need to invert the
+ − 1450 image to accomplish this; we invert if fg is
+ − 1451 odd. (Remember that WhitePixel and BlackPixel are not
+ − 1452 necessarily 1 and 0 respectively, though I think it
+ − 1453 might be safe to assume that one of them is always 1
+ − 1454 and the other is always 0. We also pretty much need to
