[R-SIG-Mac] rgl crashes after one successful draw on R.app

[Roger Koenker]

FWIW,  I'm also having difficulties with rgl since upgrading to R 3.0  

> sessionInfo()
R version 3.0.0 (2013-04-03)
Platform: x86_64-apple-darwin10.8.0 (64-bit)

locale:
[1] en_US.UTF-8/en_US.UTF-8/en_US.UTF-8/C/en_US.UTF-8/en_US.UTF-8

attached base packages:
[1] stats     graphics  grDevices utils     datasets  methods   base     

other attached packages:
[1] rgl_0.93.935

and XQuartz 2.6.5 (xorg-server 1.10.6)  as soon as I do rgl.open()  I get:

*** caught segfault ***
address 0xe8, cause 'memory not mapped'

Traceback:
 1: .C(rgl_dev_open, success = FALSE)
 2: rgl.open()
 3: open3d()
 4: eval(expr, envir, enclos)
 5: eval(ei, envir)
 6: withVisible(eval(ei, envir))
 7: source(tf, local, echo = echo, prompt.echo = paste0(prompt.prefix,     getOption("prompt")), continue.echo = paste0(prompt.prefix,     getOption("continue")), verbose = verbose, max.deparse.length = Inf,     encoding = "UTF-8", skip.echo = skips, keep.source = TRUE)

maybe this is a better hint though -- suspending the unresponsive process produced the additional message:

Warning message:
In rgl.open() : RGL: no suitable visual available

And the same thing happens if I just do the commands inside the function individually.  SessionInfo() below.
