Implement --framebuffer-size #169

Open hujiajie opened 3 years ago

Currently Aquarium renders directly to the framebuffer the window system gives to it. The framebuffer size is determined by the GLFW window size (and DPI), which means the maximum will be limited by screen size. To harness the GPU, sometimes it's desired to use an extremely large offscreen framebuffer for rendering, whose size is given by --framebuffer-size, and then "blit" to the window.

@Honry Let's track the issue here. I'm afraid it's a non-trivial change. With current code path, I'm not sure if a HiDPI screen may help.

@hujiajie, thanks for your great support! It's a nice but not must to have feature for me, so please take your time on this.

This sounds like super sampling, how about '--super-sampling'?

@JiangYizhou, thanks for the comment. --framebuffer-size stems from the term used by GLFW.
