Re: Updates on Freetype Demos - Swift Support

[Alexei Podtelezhnikov]

Hi Akhmet,

Going in the opposite order:
- grinit.c should have an entry for you new driver, which should
reside in a subfolder, which should contain rules.mk, which should
detect macOS. Once set up properly, you should have your driver
compiled in.
- grInitDevices() is the first call (see inside FTDemo_display_New).
This does not open the window yet. This only prepares for it:
RegisterClass in Windows, XOpenDisplay and get details of appropriate
Visual in X11.
- grNewSurface(...) actually opens the window of the requested size
and the requested (or default) color depth. Or returns NULL and causes
termination. The return surface object will be used for future
communication with the open window. It also hosts the frame buffer
that is projected in the windows
- grRefreshSurface does just that: looks at the surface frame buffer
and displays it
- grListenSurface communicates the key presses and window resizes so
that the main program modifies the frame buffer and back to
grRefreshSurface, etc, etc, etc
