- Introduced new header and implementation files for IME keyboard layout handling. - Added structures for viewport metrics, keyboard grid layout, and drawing parameters. - Implemented functions to compute viewport and panel metrics for the IME dialog. - Enhanced the IME dialog UI to utilize the new keyboard layout and metrics. - Updated input handling to support new keyboard interactions and layout adjustments. - Added caret management and text normalization features in the IME dialog state. - Improved window positioning logic to accommodate different screen resolutions.
