Significantly improved XIM support.
Fixes Bugzilla #429.
Selected notes from the patch's README:
= FIXES =
This patch fixes the above issues as follows.
== X11 events ==
Moved XFilterEvent just after XNextEvent so that all events are passed
to it. Also, XFilterEvent will receive masks indicated by IM through
XNFilterEvents IC value as well as masks surpplied by SDL.
X11_KeyRepeat is called between XNextEvent and XFilterEvent, after
testing an event is a KeyRelease. I'm not 100% comfortable to do so,
but I couldn't find a better timing to call it, and use of the
function is inevitable.
== Xutf8LookupString ==
Used a longer buffer to receive UTF-8 string. If it is insufficient,
a dynamic storage of the requested size will be allocated. The
initial size of the buffer is set to 32, because the Japanese text
converted from the most widely used benchmark key sequence for
Japanese IM, "WATASHINONAMAEHANAKANODESU." has ten Japanese characters
in it, that occupies 30 bytes when encoded in UTF-8.
== SDL_keysym.unicode ==
On Windows version of SDL implementation, SDL_keysym.unicode stores
UTF-16 encoded unicode characters, one UTF-16 encoding unit per an SDL
event. A Unicode supplementary characters are sent to an application
as two events. (One with a high surrogate and another with a low
surrogate.) The behavior seems reasonable since it is upward
compatible with existing handling of BMP characters.
I wrote a UTF-8 to UTF-16 conversion function for the purpose. It is
designed with the execution speed in mind, having a minimum set of
features that my patch requires.

======================== Using SDL with PicoGUI ======================== - Originally contributed by Micah Dowty <micahjd@users.sourceforge.net> PicoGUI is a scalable GUI system with a unique architecture, primarily focused on scalability to various embedded systems. You can find more information including a FAQ at http://picogui.org To use the patch: 1. When compiling, add the "--enable-video-picogui" switch to ./configure 2. When running your program, ensure that the picogui driver for SDL is in use by setting the SDL_VIDEODRIVER environment variable to "picogui". 3. The program must also be linked to the C client library for PicoGUI (libpgui.so). If the program is being compiled with a patched SDL installed this should be done automatically. If you want to use an existing binary with PicoGUI, you can set the LD_PRELOAD environment variable to the path of your libpgui.so file. Capabilities: So far only basic functionality is provided on true color (linear16/24/32) devices. Accessing a memory mapped bitmap, updating the display, and handling mouse/keyboard input. This functionality has been tested with several applications, including mplayer, Xine, sldroids, and Abuse. TODO list: - YUV overlays will be helpful for watching video on set top boxes or other embedded devices that have some graphics acceleration hardware - Account for rotated bitmap storage in pgserver - Support for hiding or changing the cursor - The display should be centered when the SDL application is smaller than the PicoGUI panel - Fullscreen or any other special modes - Support for indexed and grayscale modes - Probably much more... --- The End ---
