+The 21-pixel bitmaps are also based on Elmar's font, but I hand-tuned\r
+them quite a bit.  I converted them from the Metafont gf file by\r
+running gftype and applying a C program of my own to the\r
+human-readable output.\r
+\r
+icon_white and icon_black were produced in the same way.\r

+The 33, 45, 49, 54, and 58 pixel bitmaps are also based on Elmar's font.\r
+They were converted using dopkbm.sh, followed by a manual pass with the\r
+X bitmap editor to adjust the size (adding blank borders as needed) and\r
+to hand-tune the pixels in a few cases where that was badly needed.\r
+Here is some data that may be useful in later conversions:\r

+In each case, fselch*.mf was formatted for 300 dpi.  On Linux with the\r
+Red Hat tetex-0.4pl8-9 package, this required mag=0.5.  Example:\r
+\r
+  mf\r
+  \mode=localfont; mag=0.5; input fselch8.mf\r
+  gftopk fselch8.300gf\r
+\r
+On Red Hat with tetex-0.9-6, mag=1.0 was needed instead.\r

+I added a large number of bitmaps for non-orthodox pieces, mainly in\r
+size middling and bulky (and to a lesser extent in petite). A few pieces\r
+(Archbishop, Chancellor and Lance) are available in all sizes from petite to bulky.\r
+The bitmaps were created as WinBoard .bmp monochrome bitmaps with MS Paint, and \r
+converted to .bm C-source files semi-automatically, to be used as built-ins for xboard.\r
