specific to X windows. I changed a few names of variables and methods to
sound less X windows specific, for example in the BXKeyEntry struct
the "xwinKey" field is now called "hostKey".
- remove the hacks in bx_keymap_c::loadKeymap that checked that every
keysym started with "XK_". Now I can still make that check, but it
is done in x.cc's convertStringToXKeysym() instead.
- in sdl.cc, load the keymap in specific_init function. I had to
create a conversion function from SDL key names to SDLkey values.
I created a table of key names and associated values, and I just
do a strcmp on each name. It's not a fast algorithm obviously but this
conversion only has to be done for maybe 200 keys at startup time.
- added a key map file for SDL called sdl-pc-us.map. Since this has
basically all the SDLK_* symbols defined, it is a good starting point
if you need to make any other keymaps.
- modified: gui/keymap.cc gui/keymap.h gui/sdl.cc gui/x.cc iodev/keyboard.cc
- added: gui/sdlkeys.h gui/keymaps/sdl-pc-us.map
