[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.
     2 These are test programs for the SDL library:
     4 	testver		Check the version and dynamic loading and endianness
     5 	testtypes	Check to see if the data types are the correct size
     6 	testhread	Hacked up test of multi-threading
     7 	testlock	Hacked up test of multi-threading and locking
     8 	testerror	Tests multi-threaded error handling
     9 	testsem		Tests SDL's semaphore implementation
    10 	testtimer	Test the timer facilities
    11 	loopwave	Audio test -- loop playing a WAV file
    12 	testcdrom	Sample audio CD control program
    13 	testkeys	List the available keyboard keys
    14 	testvidinfo	Show the pixel format of the display and perfom the benchmark
    15 	checkkeys	Watch the key events to check the keyboard
    16 	testwin		Display a BMP image at various depths
    17 	graywin		Display a gray gradient and center mouse on spacebar
    18 	testsprite	Example of fast sprite movement on the screen
    19 	testbitmap	Test displaying 1-bit bitmaps
    20 	testalpha	Display an alpha faded icon -- paint with mouse
    21 	testwm		Test window manager -- title, icon, events
    22 	threadwin	Test multi-threaded event handling
    23 	testgl		A very simple example of using OpenGL with SDL
    24 	testjoystick	List joysticks and watch joystick events
    25 	testoverlay	Tests the software/hardware overlay functionality.
    26 	testoverlay2	Tests the overlay flickering/scaling during playback.
    27 	testblitspeed	Tests performance of SDL's blitters and converters.
