a lot of avatar frames attempt to turn the avatar into a different shape

but often it's visible how the avatar is actually still circle-shaped and it looks wrong (top example)

to fix this, creators should be able to supply an avatar alpha mask with their avatar frames (bottom example)

※ the avatar mask should be optional to save creators' time and Game Jolt's server memory because many avatar frames work perfectly with the default circular avatar shape

※ a lot of avatar frames are square-shaped so there should also be a square mask preset to save even more creators' time and Game Jolt's server memory
