nanogui: Thread: nano-X0.91 & nxlib0.45 & tk8.4.15

After some efforts, it works ! And it seems promising.
Thanks to Greg and others involved in these tools.

It requires a small pacth in Tk code: replace the macro QLength() by the
function XQLength()

After that basic functions seems to work.

I am facing various problem with fonts:
  a.. fonts.dir are not present in nano-X distribution (easy to generate
with mkfontdir & ttmkfdir)
  b.. Tk seems to use extensively the XFontStruct; for some fonts, the
fields min_byte1 and max_byte1 seems wrong
  c.. limitation for widths:
    a.. microwin/src/include/mwtypes.h  MWFONTINFO.widths is limited to 256
    b.. similar limitation in nxlib/QueryFont.c
    c.. consequently I made a patch in Tk to avoid accessing
XFontStruct.widths to far
I should also integrate nano-X in my linux embedded system. Hardware
includes EPSON S1D13706 controller.
Has someone integrated nano-X on that type of HW ?

Great news!  See my comments below.

OK.  I hadn't realized that this may mean we can't use Xlib applications
without recompiling...  This and possibly other macros will need
documenting in NXLIB somewhere.

:   b.. Tk seems to use extensively the XFontStruct; for some fonts, the

More details if possible?



:   c.. limitation for widths:
:     a.. microwin/src/include/mwtypes.h  MWFONTINFO.widths is limited to
256

We don't have to be limited to 256 widths, are you using a font with
more glyphs?  Can you give me an example of the patch change in
the Tk code?  This likely will have to be fixed in NXLIB for
maximum compatibility.
