    TextuePack Enhancement

    I've created the following class which is a simple TexturePack which you can draw into. It is handy for puzzle games where you might want to generate the blocks using one tile.

end
 
--- draw

-- <a href="https://forum.gideros.rocks/profile/param" rel="nofollow">@param</a> brush (Sprite) Sprite to be drawn
function TPack:draw(brush)
  local canvas = self.canvas
  canvas:clear(0, 0, brush:getX(), brush:getY(), brush:getWidth(), brush:getHeight())
  canvas:draw(brush)
end
    Would it be possible for Gideros to have this kind of functionality built in?
