Adding fixtures changes the sprite's dimension values

[quinton-ashley]

This issue was noticed by @ .froderick on Discord.

After adding a collider or sensor (planck fixture) sprite.w, for example, gets the width of the added fixture. Setting sprite.w it will set the width of the original collider though.

I think for simplicity sprite.w should just reference the width of the sprite's first collider.
