+GLSL version 1.20 is supported in Mesa 7.3.
+Among the features/differences of GLSL 1.20 are:
+<ul>
+<li><code>mat2x3, mat2x4</code>, etc. types and functions
+<li><code>transpose(), outerProduct(), matrixCompMult()</code> functions
+(but untested)
+<li>precision qualifiers (lowp, mediump, highp)
+<li><code>invariant</code> qualifier
+<li><code>array.length()</code> method
+<li><code>float[5] a;</code> array syntax
+<li><code>centroid</code> qualifier
+<li>unsized array constructors
+<li>initializers for uniforms
+<li>const initializers calling built-in functions
+</ul>
