This function loads the vertex, geometry and fragment shaders. Pass NULL if you don't want to load a specific shader. The sources must be text files containing valid shaders in GLSL language.

This function should always be called before using the geometry shader features. If it returns false, then any attempt to use sfShader geometry shader features will fail.
This function can only return true if isAvailable() would also return true, since shaders in general have to be supported in order for geometry shaders to be supported as well.

name is the name of the variable to change in the shader. The corresponding parameter in the shader must be a 4x1 vector (vec4 GLSL type).
It is important to note that the components of the color are normalized before being passed to the shader. Therefore, they are converted from range [0 .. 255] to range [0 .. 1]. For example, a sf::Color(255, 125, 0, 255) will be transformed to a vec4(1.0, 0.5, 0.0, 1.0) in the shader.
