a real pleasure, actually.  (see below)

that, I think needs .. re-stating.  :-)

I'm not a betting person, but would put good money on: if you were to create a
VM and installed either Slackware (of course!  :-)) or some BSD-derived Linux,
or Solaris, you'd find no "problems with x11"[*].  I think that rather than from
the X Windows system, problems will occur when using a Ubuntu.  (Mark
Shuttleworth tried too hard to become the "cock on the midden"  :-))  (although,
having said that, who knows, perhaps it goes back to Debian)

[*] that's not to say that the API isn't .. cumbersome, or perfect.  O'Reilly
published a really good set of references to X11R5 and X11R6.

well now, "povr -y x11 ..." works beautifully here.  :-)  the only difference I
see is that the x11 gives me window that starts with a transparent background,
while the (default) SDL2 window is black when empty.

and _I_ really like that the X functionality is making a comeback.

first impressions, have only run a handful of scenes for quick trying out that
it "just works".  fully installed ~4.2M -- nice!  it feels quite .. sprightly,
the difference to the 10064268.alpha seems to be ~5% faster parse and ~10%
faster render.

I'll play some more in the week, then post a list of .. issues.


regards, jr.
