* also be initialized here.
* Parameters:
* const char* title: window title.
* ivec2 windowsize: the size in pixels for the new window.
* const u32 flags: window flags, such as static size and fullscreen.
* The flags are platform agnostic and needs to be
* converted to the specific library
* Returns:
* A pointer to a struct Window, NULL on error.
