# NOTE: On Windows Icons -- 
# The "abbrv.rc" file is a convention needed to add an icon and other
# built-into-the-binary data on Windows. Setting the icon through
# SDL_SetWindowIcon is NOT good enough! That only sets the taskbar icon, but
# not _most_ of the other sizes. Thus, we use them both. The .png used by SDL
# is crisper, but the .ico file meets the other sizing / placement
# requirements.

# TODO: 
# WIN32 flag here disables the console which we want, but not before we've
# added an in-editor console via IMGUI
