Hello,
I'm not so terribly new to Perl but very new to SDL. I was fiddling with the
following "Hello, World!"-ish code in the SDL manual:
use strict;
use warnings;
use SDL;
use SDLx::App;
my $app = SDLx::App->new( width=> 800, height => 600 );
$app->draw_rect([ $app->width / 4, $app->height / 4,
$app->width / 2, $app->height / 2, ],
[ 0, 0, 255, 255] );
$app->update();
sleep(5);
and found that changing the alpha portion of the rectangle color (eg fading the
rectangle out completely via [0,0,255,0]) had no effect on the rendering of the
rectangle. I did some searching on this and found some

questions<http://markmail.org/message/lqtdvmmjmiryumrw#query:+page:1+mid:q63xng5hz7lpcsbl+state:results>
from 4+ years ago, but I'm wondering if there is a simple workaround or an
approach that has come about since then.
Thank you for your time,
Jack
