[idea] macOS - seamless retina window (high res or not)

[dimitre]

I finally found everything to make retina work with a seamless window.
Basically everything will work the same and only pixel density will change.

It is working great in the fork I'm using.
I'll explain what the changes are if anybody wants to port to OF.

GLFW window size and mouse will not be doubled in retina. everything is the same.
I've just removed pixelcoordscale, not relevant anymore.
we have to consider the framebuffer size and window size and have the appropriate GLFW callbacks.
ofMatrixStack::getRenderSurfaceSize() have to consider currentWindow->getFramebufferSize();

I'm using always high resolution on PLIST now, so the window decorations are not pixelated (title bar and colored buttons)
this can be switched in ofWindowSettings, so GLFW will handle the way framebuffer works.

// In this fork there is only ofWindowSettings, no inheritance for settings
	ofWindowSettings settings;
	settings.highResolutionCapable = true;

I'll keep using settings.highResolutionCapable = false for some pixel sharp fonts interface.
They can get a little bit blurry on retina. but much better for smooth fonts

Last missing detail, fixing ofDrawBitmapString, by changing

		rViewport = getCurrentViewport();

to

		rViewport = matrixStack.getFullSurfaceViewport();

@dimitre this looks like a great middle ground solution.
Def be worth a PR immediately after 0.12.1

Thanks for digging into this. I figured it was be more or less straightforward, just finding all the detailed spots to adjust to the right calls.

Great @danomatika testing is welcome
this fork has a different project generator and libs, works for macos and linux only
