+// __multiversion__
+// This signals the loading code to prepend either #version 100 or #version 300 es as apropriate.
+
+// To use centroid sampling we need to have version 300 es shaders, which requires changing:
+// attribute to in
+// varying to out when in vertex shaders or in when in fragment shaders
+// defining an out vec4 FragColor and replacing uses of gl_FragColor with FragColor
+// texture2D to texture
+#if __VERSION__ >= 300
+
+// version 300 code
+
+#define varying in
+#define texture2D texture
+out vec4 FragColor;
+#define gl_FragColor FragColor
