     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 	Window may not close when unsetting video mode and resetting.
    76 
    77 	Resizeable windows aren't implemented yet.
    78 
    79 	Depth switching for windowed mode isn't implemented yet.
    80 	
    81 	Palette handling isn't implemented in windowed mode yet.
    82 	
    83 	Command-line arguments Dialog is not implemented yet.
    84 
    85 	Fullscreen drawing has some artifacts.
    86 	
    87 	Fullscreen window covers *all* other windows - even force quit.
    88 	
    89 	Fullscreen OpenGL for the software renderer is broken.
    90 
    91 	Some OpenGL parameters are not accounted for, for example color bits customization.
    92 	
    93 	Getting OpenGL context parameters is not implemented.
    94 	
    95 	Continuous mouse motion perhaps is not as smooth as it should be.
    96 
    97 	SDL_WM_GrabInput() is implemented, but it "freezes" the hardware
    98 	cursor in the center of the window/screen.  Also, mouse moved events
    99 	are not generated, and the keyboard cannot be grabbed.
   100 
   101 	MacOS X seems to have a broken pthread_cancel() implementation.
   102 
   103 FreeBSD:
   104 	pthread_cancel() isn't supported by FreeBSD 3.X, so threads don't
   105 	work on versions of FreeBSD earlier than 4.0.
   106 
   107 	The CD-ROM handling doesn't work completely.
   108 
   109 	Wide UNICODE character input (Kanji, etc.) is not yet supported.
   110 	It requires handling of keyboard mapping events and using the XIM
   111 	input translation extension.  I will implement it as requested.
   112 	Latin-1 keyboard input works fine.
   113 
   114 	The keyboard modifiers are not set to the correct state on startup.
   115

   117 	The joystick functions are not implemented yet.
   118 
   119 	Wide UNICODE character input (Kanji, etc.) is not yet supported.

   121 	input translation extension.  I will implement it as requested.
   122 	Latin-1 keyboard input works fine.
   123 
   124 	The keyboard modifiers are not set to the correct state on startup.
   125

   127 	The CD-ROM handling doesn't work completely.
   128 
   129 	The joystick functions are not implemented yet.
   130 
   131 	Wide UNICODE character input (Kanji, etc.) is not yet supported.

   164 
   165 	The joystick subsystem isn't implemented yet.
   166

   179 
   180 QNX:  -= NOT YET SUPPORTED =-
   181 	Configuration doesn't work right, Makefiles still need to be
   182 	tweaked (need to add libraries to any apps that use sdl_config
   183 	to figure out what libs they need).
   184  
   185 	Only static libraries are being made, no shared ones.
   186  
   187 	The only hardware surface is the primary view surface.
   188

   192  
   193 	The software surfaces could use some speed up.
   194  
   195 	It doesn't look like the OpenGL stuff is there. (did a grep for
   196 	PdCreateOpenGLContext, nothing found).
   197
