* \brief A variable to control if extended IME text support is enabled.
* If enabled then SDL_TextEditingExtEvent will be issued if the text would be truncated otherwise.
* Additionally SDL_TextInputEvent will be dispatched multiple times so that it is not truncated.
*
* The variable can be set to the following values:
* "0" - Legacy behavior. Text can be truncated, no heap allocations. (default)
* "1" - Modern behavior.
