Changed method of storing WWLCDPanel data. (I made 1 byte allocated with 1 pixel as 1 byte with 2 pixels) (For speeding up, thought about future color correspondence (241 colors?)) Added WonxDisplay_Sync (). Reduced wasteful drawing in functions of get type. Implement sprite window function. (Not tested) Implement time related functions. (timer.c) Fix sprite priority. (I modified "Priority is given to younger one") Version 0.0.4 alpha - from wonx-a04.tar.gz
