 `hitbox_type` describes which type of shape the button has. `radial` (circle, ellipsis) and `rect` (rectangular) shapes are supported.
 
 `range_x` and `range_y` describe the size of the button. The semantics differ slightly for radial and rect hitbox types. For `radial` shape, `range_x` and `range_y` describe the radius in x and y directions in pixels of the source image. For `rect` shape, the `range_x` and `range_y` values represent the distance from center to the edge of the rect in terms of pixels of the source image. E.g. a `range_x` of 20 would mean the width of the rectangular is 40 pixels in total.
