1. Rewrote the display unit library in C language, now the program no longer relies on the disp.dll written in Pascal language.
2. Fixed a bug where bitmap reading failed due to incorrect referencing of GDIPLUS-related functions.
3. Fixed an issue where the screen's default device context was incorrectly released due to an erroneous release condition.
4. Fixed a problem where bitmaps could not be drawn to the device context due to being released at the wrong location.
5. Fixed an issue where WM_PAINT was not handled by the default function in the callback function, causing the message queue to resend repeatedly and the thread to get stuck.
6. Fixed a problem where animations could not be displayed during line deletion due to a type conversion error.
7. Fixed an issue where a spelling error caused the window to fail to load icon resources.
8. Fixed an issue where after minimizing and restoring, a fixed window size was set to auto.
