Hey,
tried <AnchorFill /> already, also setting up dimensions, etc. - that does not work.
<TextureCoords> do sth. different, they define to only use a section of a texture, like an imagemap in html.
@Ayantir:
Copied your mouseHandlers to my example. If defined in lua the texture will grow with the button. If defined in xml the texture will grow too, but only in relation to it's former size (probably its original size).
This behavior is really strange.
