Subject: Various objects: Use "reader_get_layer" to parse the "z-pos" and "layer" options.
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=a7655ce3981d2136fb72ddf2e1ef6156655e3c10;p=supertux.git

Various objects: Use "reader_get_layer" to parse the "z-pos" and "layer" options.

This should be a much more thorough fix for the bug described in #527 "Text and
backgrounds can overlap the menu".

References: #527.
