Hi,
I discovered that Mosaic-2.6 is broken for 16 bpp displays under
2.1/XFree86-3.1.2. The following patchfile fixes it:
*** src/pixmaps.c.orig Thu Nov 16 20:03:15 1995
--- src/pixmaps.c Thu Nov 16 20:19:23 1995
***************
*** 404,411 ****
--- 404,417 ----
datap = data;
for (w = size; w > 0; w--)
{
+ #if defined( __FreeBSD__ )
+ /* xdpyinfo: red, green, blue masks: 0xf800, 0x7e0, 0x1f */
+ temp = ( (colrs[(int)*datap].red & 0xf800) |
+ ((colrs[(int)*datap].green >> 5) & 0x07e0) |
+ #else
temp = (((colrs[(int)*datap].red >> 1) & 0x7c00) |
((colrs[(int)*datap].green >> 6) & 0x03e0) |
+ #endif /* __FreeBSD__ */
((colrs[(int)*datap].blue >> 11) & 0x001f));
if (BitmapBitOrder(XtDisplay(wid)) == MSBFirst)
