- Added 'Framebuffer'
- Added an optional 'FrameBuffer' parameter to'Renderer::BeginScene'
- Added 'RenderCommand::DefaultTargetFramebuffer()'
- Added static 'GraphicsContext::GetSharedContext()'
- Fixed 'dxBlender' by changing 'DestBlendAlpha' from D3D11_BLEND_ZERO
to D3D11_BLEND_ONE
- Fixed 'glRenderCommand::ClearBackBuffer()' by calling glClear before
glClearColor
- 'Application::GameLoop' now updates the ui ._.
