/**
 * Enumerate values used within the libvisual event system for keyboard events.
 *
 * The table is closely modelled after that of SDL and the SDL1.2 
 * SDLK defines can be directly translated to those of libvisual, however
 * some keys are left out, but these are rarely or never used.
 *
 * The basic keys are also mapped as in the ASCII table so basic
 * keyboard support is easy to implement within a libvisual client.
