I would like to create a window (win32) with the background set initially to black. Now it is white until glfwSwapBuffers is called, which causes an annoying flash. Please help=)

Solved it by setting:  
wc.hbrBackground = CreateSolidBrush( RGB(0,0,0) );  
in  
win32\_window.c -\> registerWindowClass

Would be neat if this could be set through glfwOpenWindowHint.
