/* NOTE ABOUT KEY VALUES!
 * I am using the renderer-dependent key value macros here (at least for now). This means that the
 * button mapping may be renderer-dependent. When changing renderers, make sure to backup the
 * original button mapping or something so that the user can reset it afterwards. Eventually we
 * should fix this (or maybe it's not even a problem).
