Daijiro Fukuda b0506b7912 X11: Support IME ... This commit re-organizes 6e7f93916b96c643ca7abe45d09f72d841ff15ed. * Load missing XIM related function symbols. * Generalize platform-specific features to _GLFWplatform. * Change the defalut input style to over-the-spot style. * Rename `decodeUTF8()` to `_glfwDecodeUTF8()` to make it as internal API. * It will be also needed to implment input method for Wayland. * Refactor code shapes and variable names. About over-the-spot style and on-the-spot style on X11: * In over-the-spot mode, almost all APIs are disabled since applications only need to specify the preedit candidate window position by `glfwSetPreeditCursorPos()`. * We can change the style by enabling `GLFW_X11_ONTHESPOT` init hint, but it has the following problems. * Status APIs don't work because status callbacks don't work. (at least in my ibus environment). * Can't specify the candidate window position. Known problems: * Some keys (arrow, Enter, BackSpace, ...) are passed to applications during preediting. * This will be fixed in PR #1972 : https://github.com/glfw/glfw/pull/1972 Co-authored-by: Takuro Ashie <ashie@clear-code.com>		2024-04-02 08:38:10 +09:00
