Frame bleed on tinted sprites in some situations #550
Description
When tinting certain sprites (at least the Moose) we can end up with artifacts from adjacent frames. You can see them flickering in this animation at the edges of the green moose.
Noticed on https://studio.code.org/projects/dance/40Pkt9eperMbkUY8c1KMldHZsnWrBU8c3ng3ofN9YOM/view
The solution is to add a pixel or two of additional padding between frames when we pack the spritesheets. TexturePacker already has a setting for this.
