Subject: Patches for tests and QNX6

Here more fixes for the QNX6 in sdlqnx.diff file:

- Spellchecked README.QNX (thanks to Julian Kinraid)
- Fixed bugs in fullscreen mode: window region wasn't on top by default, so \
it caused some artifacts to be appeared on the screen, prevent window conten\
ts default filler in Photon while in fullscreen mode, it damages the screen.
- Added support for the SDL_VIDEO_WINDOW_POS, SDL_VIDEO_CENTERED env variabl\
es.
- Some minor code restructurization.
     1 
     2 All:
     3 	Audio rate conversion is only implemented by multiplying or dividing
     4 	by a power of two.  This is a side-effect of the requirement that the
     5 	raw audio buffer size be a power of two, and can hopefully be fixed.
     6 	This means 8 KHz audio converted to 22 KHz ends up being 16 KHz. :-/
     7 
     8 	When the implementation is writing directly to video memory the mouse
     9 	cursor doesn't work properly.  Applications which do this should use
    10 	their own mouse cursor and call SDL_ShowCursor(0) to hide the system
    11 	cursor.
    12 
    13 Linux:
    14 	Wide UNICODE character input (Kanji, etc.) is not yet supported.
    15 	It requires handling of keyboard mapping events and using the XIM
    16 	input translation extension.  I will implement it as requested.
    17 	Latin-1 keyboard input works fine.
    18 
    19 	The keyboard modifiers are not set to the correct state on startup.
    20 
    21 	The AAlib, GGI, and SVGAlib video drivers are not heavily tested.
    22 
    23 Win32:
    24 	The MCI driver can't tell if the CD-ROM drive is paused or stopped.
    25 
    26 	The SDL_INIT_EVENTTHREAD flag is not supported on Win32
    27 	(Idea: create a separate DirectInput polling thread)
    28 	The main purpose of this flag is for smooth cursor motion in
    29 	fullscreen environments.
    30 
    31 	Wide UNICODE character input (Kanji, etc.) is not yet supported.
    32 	This requires the ToUnicode() API which is only implemented on
    33 	Windows NT/2000, not on Windows 95/98.
    34 	Latin-1 keyboard input works fine.
    35 
    36 	Joysticks are only supported under the Win32 MultiMedia API,
    37 	DirectInput support is not yet implemented.
    38 
    39 BeOS:
    40 	BePPC is not supported, apparently not even by Be Inc.
    41 
    42 	SDL_WM_GrabInput() is not implemented.
    43 	Does anyone know how to do this?  SDL_WM_GrabInput() is designed
    44 	to prevent the user from switching input and mouse focus away from
    45 	the SDL application.
    46 
    47 	Continuous relative mouse motion is not implemented.
    48 
    49 	Wide UNICODE character input (Kanji, etc.) has not been tested.
    50 	Latin-1 keyboard input works fine.
    51 
    52 MacOS:
    53 	Palette handling isn't implemented in windowed mode yet.
    54 
    55 	Audio hasn't been extensively tested, in particular the locking
    56 	isn't implemented and mixer routines may not call malloc() or free()
    57 	because they are called at interrupt time.
    58 
    59 	SDL_WM_GrabInput() is not implemented.
    60 	Does anyone know how to do this?  SDL_WM_GrabInput() is designed
    61 	to prevent the user from switching input and mouse focus away from
    62 	the SDL application.
    63 
    64 	Continuous relative mouse motion is not implemented.
    65 
    66 	SDL_AddTimer() and SDL_RemoveTimer() haven't been implemented yet.
    67 
    68 	Not all of the keys are properly recognized on the keyboard.
    69 
    70 MacOS X:
    71 	CD-ROM functions are not implemented yet.
    72 
    73 	Joystick code is not extensively tested yet.
    74 
    75 	Resizeable windows aren't implemented yet.
    76 
    77 	Depth switching for windowed mode isn't implemented yet.
    78 	
    79 	Palette handling isn't implemented in windowed mode yet.
    80 	
    81 	Command-line arguments dialog is not implemented yet.
    82 
    83 	Fullscreen drawing has some artifacts.
    84 	
    85 	Fullscreen OpenGL for the software renderer is broken.
    86 
    87 	Some OpenGL parameters are not accounted for, for example color bits customization.
    88 	
    89 	Continuous mouse motion perhaps is not as smooth as it should be.
    90 
    91 	SDL_WM_GrabInput() is implemented, but it "freezes" the hardware
    92 	cursor in the center of the window/screen.  Also, mouse moved events
    93 	are not generated, and the keyboard cannot be grabbed.
    94 
    95 	MacOS X seems to have a broken pthread_cancel() implementation.
    96 
    97 FreeBSD:
    98 	pthread_cancel() isn't supported by FreeBSD 3.X, so threads don't
    99 	work on versions of FreeBSD earlier than 4.0.
   100 
   101 	The CD-ROM handling doesn't work completely.
   102 
   103 	Wide UNICODE character input (Kanji, etc.) is not yet supported.
   104 	It requires handling of keyboard mapping events and using the XIM
   105 	input translation extension.  I will implement it as requested.
   106 	Latin-1 keyboard input works fine.
   107 
   108 	The keyboard modifiers are not set to the correct state on startup.
   109 
   110 Solaris:
   111 	The joystick functions are not implemented yet.
   112 
   113 	Wide UNICODE character input (Kanji, etc.) is not yet supported.
   114 	It requires handling of keyboard mapping events and using the XIM
   115 	input translation extension.  I will implement it as requested.
   116 	Latin-1 keyboard input works fine.
   117 
   118 	The keyboard modifiers are not set to the correct state on startup.
   119 
   120 IRIX:
   121 	The CD-ROM handling doesn't work completely.
   122 
   123 	The joystick functions are not implemented yet.
   124 
   125 	Wide UNICODE character input (Kanji, etc.) is not yet supported.
   126 	It requires handling of keyboard mapping events and using the XIM
   127 	input translation extension.  I will implement it as requested.
   128 	Latin-1 keyboard input works fine.
   129 
   130 	The keyboard modifiers are not set to the correct state on startup.
   131 
   132 EPOC:
   133     Only Crystal version of Epoc/SymbianOS is currently supported.
   134 
   135     SDL is implemented in static library only. SDL uses static/global
   136     variables and that is not allowed in EPOC dll libraries.
   137 
   138     Sound is not yet supported.
   139 
   140     Joystick, OpenGL and cdrom is not supported (think about cdrom in a cell phone:-).

   142     No console output screen. Printing to stdout do not have any effect.
   143

   174
