Devdraw: 3 other bugs resolved?

Devdraw's new function "drawresizehandle" should
draw the grabber on top of Plan9's image on Snow
Leopard.  I tested it succesfully on Lion.

Devdraw now calls "[NSAutoreleasePool new]".  Does
it silence them?  (I can't verify: they don't
appear on Lion.)

It was something Devdraw was doing.  I tried to
fix it: I can't verify it; I hope I didn't break
anything.  If it works and if the following is
possible, could you also try to send a fullscreen
app from one screen to another (preferably of
different resolutions), if you please?


I'm full time on Devdraw from now on, and I'm
eager to finish it :)


Thank you for your kind words Russ.  You and Rob
Pike, are the 2 programmers I admire the most.

(I should have said:

	[...], if you please, to see if the autohiding
	is updated accordingly.)

Thanks for the quick response.
I won't be at a dual-screen Mac again
until Monday, but I will try it then.

On Lion the only remaining issue in the
whole tree is the thread crashes, right?

Thanks again.

Thanks.  This is a definite improvement.
Is it possible to draw the grabber with transparency?
I've attached a screen shot that shows acme's
grabber atop Chrome's grabber.  Maybe Chrome's
grabber looks okay because the window is white.
(Actually, no, if you delete the column in acme
then you have a white column but you can still
see the square outline.)

I changed the INSTALL script to run mk -k install
so that the failing-to-build macargv does not keep
devdraw from being installed.  Any ideas about
making macargv work?  That program took me
a good day or two to work out; the solution might
be to just delete it, but then you can't use Plumb.app.

Thanks again.
Russ
