"CHARSET_ORDER", is for converting codepage to ordinal charset num,
  and the second, "SAMPLE_LANG_TEXT", is for giving the actual sample
  text.
- Removed all references to changing the font directly in stc5.
- Modified the "InvalidateRect" calls to invalidate the rect where
  stc5 is, rather than stc5 itself.
- Added handling of WM_PAINT that draws the sample text, properly
  truncated.
- Removed handling of WM_CTLCOLOR - no longer neccessary.
