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.

The above are batched together into a single draw call when called without other drawing calls in between, as long as the following criteria are met:
- The texture is the same.
- The primitive type is the same (points cannot be batched with non-points).
- The love.graphics state is the same (aside from the current color - i.e. setColor - and the transform state).
- The active shader’s uniform values are the same.
You can examine the ‘drawcalls’ field of love.graphics.getStats() to help determine if your code is allowing for optimum batching.
