Cleaner implementation of support dynamic resizing aspect ratio (#228)

fayaz12g · web-flow · commit 0b1e51f62031 · 2026-03-03T10:11:16.000+07:00
* Add dynamic resolution

* Clean up implementation

* Use existing ints instead of new ones

* Remove WM_SIZE argument (unecessary now that we directly use g_iScreenWidth and g_iScreenHeight)
