// Calling glGetProgramiv(...GL_LINK_STATUS...) will force linking of the program at this moment.
// Otherwise, they might be linked when they are used for the first time. (I guess this depends on the driver implementation)
// So it might slow down the "booting" process on certain devices. But, on the other hand it is important to know if the shader
// linked succesfully. Some shaders might be downloaded in runtime so, release version should have this check.
// For more info, see Github issue #16231
