Subject: Re: [SDL] Question about SDL_FillRect()
I benchmarked with and without clipping UpdateRects and was unable to find
any difference on my moderately slow machine. Anyway, I haven't added
clipping in this patch, but fixed a couple of bugs and generally cleaned
up some of the X11 image code. Most importantly, UpdateRects now checks
for both zero height and width. Also, I eliminated the entire code to
byteswap X11 images since X11 can do that automatically if you ask it
nicely :-)

| 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. | |

| 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. | |

| 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. | |

| 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. | |
