Use more recent version of imgui?

[davideps]

Olivia, thank you so much for putting this starter code together! Is there any interest in making it compatible with a more recent imgui API? I changed a few cargo lines as recommended here:

imgui = "0.3.0"
imgui-gfx-renderer = "0.3.0"
imgui-winit-support = "0.3.0"

The compiler reported the following 16 errors:

[iolivia]

yep, definitely should upgrade to a more recent version. I'll take a look!

@davideps @iolivia imgui v0.4.0 require ui for build, not for new. https://docs.rs/imgui/0.4.0/imgui/struct.Image.html

      if let Some(texture_id) = self.texture_id {
        let image = Image::new(texture_id, [100.0, 100.0]);

        // Window with texture
        Window::new(im_str!("Hello textures"))
          .size([150.0, 150.0], imgui::Condition::FirstUseEver)
          .position([300.0, 150.0], imgui::Condition::FirstUseEver)
          .build(&ui, || {
            image.build(&ui);
          });
      }
