Bug description: imagecreatetruecolor black background makes alpha transparancy
unusable
Description:
------------
when creating a new truecolor image, the image gets set with a black
background. This makes it unusable to blend alpha transparant png's onto
it (for creating transparant thumbnails for example). Normally you would
have a blank (all transparant) image when creating a new image because no
data has been added to it.
Reproduce code:
---------------
$img = imagecreatetruecolor(50,50);
header ("Content-type: image/x-png");
imagepng($img);
imagedestroy($img);
Expected result:
----------------
a transparant 50x50 png image.
Actual result:
--------------
a black 50x50 png image
