4.1.6
+ In config.4coder "bind_by_physical_key" uses a key-layout that does not change with language
+ Deprecated GlyphFlag_Rotate90, rotation of immediate mode text is entirely derived from the delta vector
+ Fix: notepad like mode scrolling only creates selection when holding mouse L-buttoon
+ Fix: on windows the window has the 4coder icon
+ Fix: by default platform layer uses key codes arranged by the system language
