To use GLSL 3 in a shader, the first line of the shader has to be: #pragma language glsl3 glsl1 is the default language. Added “glsl3” graphics feature as part of the table returned by love.graphics.getSupported(). Added love.graphics.validateShader(boolean gles, shadercode). It returns a boolean along with an error string if the shader code has errors for its target language and platform (gles or desktop). Implemented support for Core Profile OpenGL 3.3 in love.graphics. --HG-- branch : minor
