With DirectX, the graphics driver cannot be determined until the main loop starts, as a transparent window cannot be treated with DirectX so far. On the other hand, compiling shaders requires a graphics driver as it requires information about Y directions of NDCs and framebuffers. This change delays compiling shaders until the graphics commands are actually executed in the main loop. Updates #1007 Updates #2019
