+<p>
+These can be overridden by using the <tt>--with-max-width</tt> and
+<tt>--with-max-height</tt> options.  The two need not be equal.

+Do note that Mesa uses these values to size some internal buffers,
+so increasing these sizes will cause Mesa to require additional
+memory.  Furthermore, increasing these limits beyond <tt>4096</tt>
+may introduce rasterization artifacts; see the leading comments in
+<tt>src/mesa/swrast/s_tritemp.h</tt>.
