New Framebuffer keeps initial one's size.

Running through old samples we were testing during the beta and noticed that this example doesn't have the framebuffer fill the window anymore after it's been "resized".

#include "UltraEngine.h"
#include "ComponentSystem.h"

using namespace UltraEngine;

int main(int argc, const char* argv[])
{
    //Get the displays
    auto displays = GetDisplays();

    //Create a window
    auto window = CreateWindow("Ultra Engine - Normal", 0, 0, 1280, 720, displays[0], WINDOW_CENTER | WINDOW_TITLEBAR);

    //Create a world
    auto world = CreateWorld();

    //Create a framebuffer
    auto framebuffer = CreateFramebuffer(window);

    //Create a camera
    auto camera = CreateCamera(world);
    camera->SetClearColor(0.125);
    camera->SetFov(70);
    camera->SetPosition(0, 0, -3);
    camera->SetViewport(200, 0, framebuffer->size.x - 200, framebuffer->size.y);

    auto uiCamera = CreateCamera(world, PROJECTION_ORTHOGRAPHIC);
    uiCamera->SetRenderLayers(2);
    uiCamera->SetClearMode(CLEAR_DEPTH);
    uiCamera->SetPosition((float)framebuffer->size.x * 0.5f, (float)framebuffer->size.y * 0.5f, 0);
    auto ui = CreateInterface(world, LoadFont("Fonts/arial.ttf"), iVec2(200, framebuffer->size.y));
    ui->SetRenderLayers(2);

    auto sz = ui->root->ClientSize();
    auto listbox = CreateListBox(5, 5, sz.x - 10, 200, ui->root, LISTBOX_DEFAULT)->As<ListBox>();
    auto tabber = CreateTabber(5, 205, sz.x - 10, sz.y - 205, ui->root)->As<Tabber>();
    tabber->AddItem("Settings", true);
    tabber->AddItem("Output");
    tabber->SetLayout(1, 0, 1, 1);

    for (int i = 0; i < 100; i++)
    {
        listbox->AddItem("Item " + String(i));
    }

    //Create a light
    auto light = CreateBoxLight(world);
    light->SetRotation(35, 45, 0);
    light->SetRange(-10, 10);

    //Create a box
    auto box = CreateBox(world);
    box->SetColor(0, 0, 1);

    //Entity component system
    auto actor = CreateActor(box);
    auto component = actor->AddComponent<Mover>();
    component->rotation.y = 45;

    //Main loop
    while (window->Closed() == false and window->KeyDown(KEY_ESCAPE) == false)
    {
        while (PeekEvent())
        {
            auto ev = WaitEvent();
            ui->ProcessEvent(ev);

            switch (ev.id)
            {
            case UltraEngine::EVENT_WINDOWCLOSE:
                if (ev.source == window) exit(0);
                break;

            default:
                break;
            }
        }

        // Rebuild the window.
        if (window->KeyDown(KEY_SPACE))
        {
            static bool bSwapped = false;
            framebuffer = NULL;
            window = NULL;

            if (!bSwapped)
            {
                // Make it a tad bigger
                window = CreateWindow("Ultra Engine - Resized", 0, 0, 1400, 800, displays[0], WINDOW_CENTER | WINDOW_TITLEBAR);
                framebuffer = CreateFramebuffer(window);
            }
            else
            {
                window = CreateWindow("Ultra Engine - Normal", 0, 0, 1280, 720, displays[0], WINDOW_CENTER | WINDOW_TITLEBAR);
                framebuffer = CreateFramebuffer(window);
            }

            // Reposition the camera.
            uiCamera->SetPosition((float)framebuffer->size.x * 0.5f, (float)framebuffer->size.y * 0.5f, 0);

            //Resize the interface
            ui->SetSize(iVec2(200, framebuffer->size.y));

            bSwapped = !bSwapped;
        }

        world->Update();
        if (framebuffer) world->Render(framebuffer);
    }
    return 0;
}

Confirmed...

camera->SetViewport(200, 0, framebuffer->size.x - 200, framebuffer->size.y);

If you call that code again after the new framebuffer is created, it works perfectly.

Ok, now there's an extra step but it makes sense.
