[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.

[dimitre]

Great @danomatika testing is welcome this fork has a different project generator and libs, works for macos and linux only https://github.com/dimitre/ofworks/

[dimitre]

Retina support is 99% ready. if anybody can jump and help with 3d camera matrix multiplication adjustment it would be great! cc @openframeworks/2d-3d

Wow - awesome work @dimitre !! Did you get TTF fonts figured out to? For me that was the biggest hurdle.

I can have a look at the camera stuff. Do you have a branch for this?

[dimitre]

Yes it is working in ofworks fork instructions to bootstrap installation on this link https://github.com/dimitre/ofworks/

or if you prefer just clone this branch https://github.com/dimitre/openframeworks/tree/ofworks

Other changes in this fork are needed, since I fixed some stuff in GLFW Window. Everything draws with correct dimensions, but ofTexture is drawing with non retina resolutions. It would be great to add a parameter to ofTexture (and ofFbo) to have variable internal density.

About Typography I think we should not handle internally anymore, just keep as it is until the time to rewrite using external libs
