Subject: All QNX patches

whole patches concerning QNX. Almost all code has been rewritten by Julian
and me. Added initial support for hw overlays in QNX and many many others
fixes.

P.S. This patches has been reviewed by Dave Rempel from QSSL and included in
SDL 1.2.5 distribution, which coming on 3rd party CD for newest 6.2.1
version of QNX, which will be available soon.

All:
slouken@0
     3
	Audio rate conversion is only implemented by multiplying or dividing
slouken@0
     4
	by a power of two.  This is a side-effect of the requirement that the
slouken@0
     5
	raw audio buffer size be a power of two, and can hopefully be fixed.
slouken@0
     6
	This means 8 KHz audio converted to 22 KHz ends up being 16 KHz. :-/
slouken@0
     7
slouken@0
     8
	When the implementation is writing directly to video memory the mouse
slouken@0
     9
	cursor doesn't work properly.  Applications which do this should use
slouken@0
    10
	their own mouse cursor and call SDL_ShowCursor(0) to hide the system
slouken@0
    11
	cursor.
slouken@0
    12
slouken@0
    13
Linux:
slouken@0
    14
	Wide UNICODE character input (Kanji, etc.) is not yet supported.
slouken@0
    15
	It requires handling of keyboard mapping events and using the XIM
slouken@0
    16
	input translation extension.  I will implement it as requested.
slouken@0
    17
	Latin-1 keyboard input works fine.
slouken@0
    18
slouken@27
    19
	The keyboard modifiers are not set to the correct state on startup.
slouken@27
    20
slouken@0
    21
	The AAlib, GGI, and SVGAlib video drivers are not heavily tested.
slouken@0
    22
slouken@0
    23
Win32:
slouken@0
    24
	The MCI driver can't tell if the CD-ROM drive is paused or stopped.
slouken@0
    25
slouken@0
    26
	The SDL_INIT_EVENTTHREAD flag is not supported on Win32
slouken@0
    27
	(Idea: create a separate DirectInput polling thread)
slouken@0
    28
	The main purpose of this flag is for smooth cursor motion in
slouken@0
    29
	fullscreen environments.
slouken@0
    30
slouken@0
    31
	Wide UNICODE character input (Kanji, etc.) is not yet supported.
slouken@0
    32
	This requires the ToUnicode() API which is only implemented on
slouken@0
    33
	Windows NT/2000, not on Windows 95/98.
slouken@0
    34
	Latin-1 keyboard input works fine.
slouken@0
    35
slouken@0
    36
	Joysticks are only supported under the Win32 MultiMedia API,
slouken@0
    37
	DirectInput support is not yet implemented.
slouken@0
    38
slouken@0
    39
BeOS:
slouken@0
    40
	BePPC is not supported, apparently not even by Be Inc.
slouken@0
    41
slouken@0
    42
	SDL_WM_GrabInput() is not implemented.
slouken@0
    43
	Does anyone know how to do this?  SDL_WM_GrabInput() is designed
slouken@0
    44
	to prevent the user from switching input and mouse focus away from
slouken@0
    45
	the SDL application.
slouken@0
    46
slouken@0
    47
	Continuous relative mouse motion is not implemented.
slouken@0
    48
slouken@0

MacOS:
slouken@0
    53
	Palette handling isn't implemented in windowed mode yet.
slouken@0
    54
slouken@0
    55
	Audio hasn't been extensively tested, in particular the locking
slouken@0
    56
	isn't implemented and mixer routines may not call malloc() or free()
slouken@0
    57
	because they are called at interrupt time.
slouken@0
    58
slouken@0
    59
	SDL_WM_GrabInput() is not implemented.
slouken@0
    60
	Does anyone know how to do this?  SDL_WM_GrabInput() is designed
slouken@0
    61
	to prevent the user from switching input and mouse focus away from
slouken@0
    62
	the SDL application.
slouken@0
    63
slouken@0
    64
	Continuous relative mouse motion is not implemented.

slouken@0
    82
slouken@47
    83
	Fullscreen drawing has some artifacts.
slouken@47
    84
	
slouken@47
    85
	Fullscreen OpenGL for the software renderer is broken.
slouken@0
    86
slouken@47
    87
	Some OpenGL parameters are not accounted for, for example color bits customization.
slouken@47
    88
	
slouken@47
    89
	Continuous mouse motion perhaps is not as smooth as it should be.
slouken@0
    90
slouken@47
    91
	SDL_WM_GrabInput() is implemented, but it "freezes" the hardware
slouken@47
    92
	cursor in the center of the window/screen.  Also, mouse moved events
slouken@47
    93
	are not generated, and the keyboard cannot be grabbed.
slouken@0
    94
slouken@0
    95
	MacOS X seems to have a broken pthread_cancel() implementation.
slouken@0
    96
slouken@0
    97
FreeBSD:
slouken@0
    98
	pthread_cancel() isn't supported by FreeBSD 3.X, so threads don't
