// 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
#else
// version 100 code
#endif
