Added initial support for Quartz video (thanks Darrell!)
     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 	The CD driver doesn't detect SCSI CD-ROMs yet.
    50 
    51 	Wide UNICODE character input (Kanji, etc.) has not been tested.
    52 	Latin-1 keyboard input works fine.
    53 
    54 MacOS:
    55 	Palette handling isn't implemented in windowed mode yet.
    56 
    57 	Audio hasn't been extensively tested, in particular the locking
    58 	isn't implemented and mixer routines may not call malloc() or free()
    59 	because they are called at interrupt time.
    60 
    61 	SDL_WM_GrabInput() is not implemented.
    62 	Does anyone know how to do this?  SDL_WM_GrabInput() is designed
    63 	to prevent the user from switching input and mouse focus away from
    64 	the SDL application.
    65 
    66 	Continuous relative mouse motion is not implemented.
    67 
    68 	SDL_AddTimer() and SDL_RemoveTimer() haven't been implemented yet.
    69 
    70 	Not all of the keys are properly recognized on the keyboard.
    71 
    72 MacOS X:
    73 	Joystick and CD-ROM functions are not implemented yet.
    74 
    75 	Closing window from window's close widget not implemented yet.
    76 	
    77 	Minimizing the window erases the framebuffer to the pinstripe pattern.
    78 	
    79 	Window may not close when unsetting video mode and resetting.
    80 	
    81 	Depth switching for windowed mode isn't implemented yet.
    82 	
    83 	Palette handling isn't implemented in windowed mode yet.
    84 	
    85 	Command-line arguments Dialog is not implemented yet.
    86 
    87 	Fullscreen drawing has some artifacts.
    88 	
    89 	Fullscreen window covers *all* other windows - even force quit.
    90 	
    91 	Fullscreen OpenGL for the software renderer is broken.
    92 
    93 	Some OpenGL parameters are not accounted for, for example color bits customization.
    94 	
    95 	Getting OpenGL context parameters is not implemented.
    96 	
    97 	Continuous mouse motion perhaps is not as smooth as it should be.
    98 
    99 	SDL_WM_GrabInput() is implemented, but it "freezes" the hardware
   100 	cursor in the center of the window/screen.  Also, mouse moved events
   101 	are not generated, and the keyboard cannot be grabbed.
   102 
   103 	Not all of the keys are properly recognized on the keyboard.
   104 
   105 	MacOS X seems to have a broken pthread_cancel() implementation.
   106 
   107 FreeBSD:
   108 	pthread_cancel() isn't supported by FreeBSD 3.X, so threads don't
   109 	work on versions of FreeBSD earlier than 4.0.
   110 
   111 	The CD-ROM handling doesn't work completely.
   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

   127 
   128 	The keyboard modifiers are not set to the correct state on startup.
   129

   183 
   184 QNX:  -= NOT YET SUPPORTED =-
   185 	Configuration doesn't work right, Makefiles still need to be
   186 	tweaked (need to add libraries to any apps that use sdl_config
   187 	to figure out what libs they need).
   188  
   189 	Only static libraries are being made, no shared ones.
   190  
   191 	The only hardware surface is the primary view surface.
   192  
   193 	Mouse events don't seem to be working right.

   196  
   197 	The software surfaces could use some speed up.
   198  
   199 	It doesn't look like the OpenGL stuff is there. (did a grep for
   200 	PdCreateOpenGLContext, nothing found).
