Hmm. Shouldn't in fact GetDeviceCaps (hdc, NUMCOLORS) always be <= 256?

According to http://msdn.microsoft.com/en-us/library/dd144877(v=vs.85).aspx

  NUMCOLORS
  Number of entries in the device's color table, if the device has a
color depth of no more than 8 bits per pixel. For devices with greater
color depths, 1 is returned.

(It says "1", but it's a typo for "-1".)
