Sprite edges getting cropped

Hi,

I notised pixels at the edges of my sprites are getting cropped,

adding a 5 px margin around the textured areas have fixed it,

but it still seems odd so i wanted to report it incase there's a bug somewhere.

var grass_SPM = new BABYLON.SpriteManager("grass", "./grass.png", 2500, 400, scene);

zoomed screenshot, original is 400*400 (transparent area above the texture)

as can be seen on the following screenshot, the top is fine, but both left, right and bottom are being chopped. (the visible seams are just a missing adjustment from changing sprite size)
