[PATCH] SDL_GetVideoMode() does not find best mode, part 2

Following commit 1.51, I come accross a problem when SDL must choose between
several video modes that could suit the one asked.

If I ask 320x240 with this list:
768x480 768x240 640x400 640x200 384x480 384x240 320x400 320x200

The smallest selectables modes are 384x240 and 320x400. And SDL choose the later
in this list, but 384x240 is more suitable. So I added a check to compare
the pixel count (surface) of modes, and select the one which has the smallest
pixel count.

In my example, 384x240 has 92160 pixels, and 320x400 has 128000 pixels. So now
SDL will choose 384x240 for the asked 320x240 mode.

     3 Using the Simple DirectMedia Layer with MacOS 7,8,9 on PPC
     4 ==============================================================================
     5 
     6 These instructions are for people using the Apple MPW environment:
     7 http://developer.apple.com/tools/mpw-tools/
     8 
     9 CodeWarrior projects are available in the CWprojects directory.
    10 
    11 ==============================================================================
    12 I.  Building the Simple DirectMedia Layer libraries:
    13     (This step isn't necessary if you have the SDL binary distribution)
    14 
    15   First, unpack the MPWmake.sea.hqx archive and move SDL.make into the
    16   SDL directory.
    17 
    18   Start MPW
    19 
    20   Set the current directory within MPW to the SDL toplevel directory.
    21 
    22   Build "SDL"  (Type Command-B and enter "SDL" in the dialog)
    23 
    24   If everything compiles successfully, you now have the PPC libraries
    25   "SDL" and "SDLmain.o" in the 'lib' subdirectory.
    26 
    27 ==============================================================================
    28 II. Building the Simple DirectMedia Layer test programs:
    29 
    30   First, unpack the MPWmake.sea.hqx archive, move the new rsrc directory to
    31   the main SDL directory, and move the makefiles in the new test subdirectory
    32   to the SDL 'test' subdirectory.
    33 
    34   Start MPW
    35 
    36   Set the current directory within MPW to the SDL 'test' subdirectory.
    37 
    38   Build the programs that have an associated MPW makefile (file ending
    39   with .make), including "testwin", "testalpha", and "graywin".
    40 
    41   Copy the SDL library file into the test directory, and run!
    42 
    43 ==============================================================================
    44 III. Building the Simple DirectMedia Layer demo programs:
    45 
    46   Copy one of the test program Makefiles to the demo directory
    47   and modify it to match the sources in the demo.
    48

    50 IV.  Enjoy! :)

    52   If you have a project you'd like me to know about, or want to ask questions,
    53   go ahead and join the SDL developer's mailing list by sending e-mail to:
    54 
    55 	sdl-request@libsdl.org
    56 
    57   and put "subscribe" into the subject of the message. Or alternatively you
    58   can use the web interface:
