Fixed bug 1582 - Allow disabling SDL_VIDEO_DRIVER_WINDOWS

Marcus von Appen

Trying to build SDL 2.x (HG) on Win32 platforms with either VS.NET or MinGW requires one to have the video subsystem and SDL_VIDEO_DRIVER_WINDOWS flag enabled due to the helper window creation routines.

The attached patch changes the helper window creation behaviour, so that one can build SDL2 without the video subsystem or Windows video drivers on Win32 platforms.

* Porting To A New Platform

  The first thing you have to do when porting to a new platform, is look at
slouken@1484
     5
include/SDL_platform.h and create an entry there for your operating system.
slouken@1484
     6
The standard format is __PLATFORM__, where PLATFORM is the name of the OS.

Ideally SDL_platform.h will be able to auto-detect the system it's building
slouken@1484
     8
on based on C preprocessor symbols.

There are two basic ways of building SDL at the moment:
slouken@1484
    11
slouken@1484
    12
1. The "UNIX" way:  ./configure; make; make install
slouken@1484
    13
slouken@1484
    14
   If you have a GNUish system, then you might try this.  Edit configure.in,
slouken@1484
    15
   take a look at the large section labelled:
slouken@1484
    16
	"Set up the configuration based on the target platform!"
slouken@1484
    17
   Add a section for your platform, and then re-run autogen.sh and build!

2. Using an IDE:

    21
   If you're using an IDE or other non-configure build system, you'll probably
slouken@1484
    22
   want to create a custom SDL_config.h for your platform.  Edit SDL_config.h,
slouken@1484
    23
   add a section for your platform, and create a custom SDL_config_{platform}.h,
slouken@1484
    24
   based on SDL_config.h.minimal and SDL_config.h.in
slouken@1484
    25
slouken@1484
    26
   Add the top level include directory to the header search path, and then add
slouken@1484
    27
   the following sources to the project:
slouken@1484
    28
	src/*.c

Once you have a working library without any drivers, you can go back to each
slouken@1484
    54
of the major subsystems and start implementing drivers for your platform.
