[PATCH] SDL_GetVideoMode() do not find the best video mode The current GetVideoMode() function stops at the first mode which has any dimensions smaller than the one asked, and gives the previous in the list. If I ask 336x224 with this list: 768x480 768x240 640x400 640x200 384x480 384x240 320x400 320x200 SDL will give me 640x400, because 640x200 as height smaller than what I asked. However the best mode is the smaller which has both dimensions bigger than the one asked (384x240 in my example). This patch fixes this, plus it does not rely on a sorted video mode list.

Using the Simple DirectMedia Layer with EPOC/SymbianOS 6.0
==============================================================================

==============================================================================
I.  Building the Simple DirectMedia Layer libraries:

  You can get Symbian SDK from: 
    http://www.symbian.com.
 
  First create "Epoc" directory under SDL main directory and unpack 
  EpocBuildFiles.zip in it.
   
  To build the librarys goto "epoc" directory and type:
    bldmake bldfiles
    abld makefile vc6 (for creating Microsoft Visual C++ makefiles)
    abld build wins udeb (building for wins emulator)
    abld build armi urel (building for real device)

==============================================================================
II. Building the Simple DirectMedia Layer programs:

  Building SDL test programs is easy once you have built the libraries:
    abld test build wins udeb
    abld test build armi urel

  Supported real screen resolutions
    320 x 200 x  8 bit
    320 x 200 x 12 bit
    640 x 200 x  8 bit
    640 x 200 x 12 bit
  Supported "emulated" screen resolutions 
    640 x 400 x  8 bit
    640 x 400 x 12 bit
    640 x 480 x  8 bit
    640 x 480 x 12 bit
  "Emulated" resolutions are implemented by by shrinking the screen vertically 
  i.e. only every second scanline is drawn. This is mainly ment to be used for 
  testing quick ports of programs. Using faked resolutions is a waste of memory 
  and cpu power!

==============================================================================
III. Running test programs

  Copy executable to the device and run it from the File manager.   The Esc 
  key quits demo programs. In Crystal, Exe programs do not appear in task list 
  nor in Extras :-(. Test programs are tested in Nokia 9210 Communicator.

  Special keys used in SDL:
    The Caps lock key enables or disables the virtual cursor. 
    Function keys are mapped as follows: 
    F1=chr+q, F2=chr+w,..., F8=chr+i, 
    F9=chr+a,..., F12=chr+d.

==============================================================================
IV.  Enjoy! :)

  If you have a project you'd like me to know about, or want to ask questions,
  go ahead and join the SDL developer's mailing list by sending e-mail to:

	sdl-request@libsdl.org

  and put "subscribe" into the subject of the message. Or alternatively you
  can use the web interface:

	http://www.libsdl.org/mailman/listinfo/sdl

  You can find more info about Epoc version of SDL from Hannu Viitala's 
  homepage
