[PEPr] Changes in proposal for Images::Image_3D

Tobias Schlitt (http://pear.php.net/user/toby) has edited the proposal for Images::Image_3D. Change comment: Just a small hint before moving on to "Call for votes" phase: The idea of Image_Canvas and shared drivers between graphic packages sounds pretty promising, but since Image_3D will first be released alpha, a switch to an Image_Canvas backend can follow after that package has been accepted. Kore will take a deeper look at that later on. Please review the proposal: http://pear.php.net/pepr/pepr-proposal-show.php?id=261 -- Sent by PEPr, the automatic proposal system at http://pear.php.net
