Changes: * Create render library (move util/render.cpp to render/render.cpp) * Move app::Zoom class to render::Zoom * Remove doc::Image::merge() member function * Add gfx::Clip helper class (to clip dst/src rectangles before a blit) * Move doc::composite_image() to render::composite_image() * Remove doc::Sprite::render() * Replace Sprite::getPixel() with render::get_sprite_pixel() * Remove doc::layer_render() function * Convert DitheringMethod to a enum class * Add AppRender to configure a render::Render with the app configuration * Move checked background preferences as document-specific configuration * Add doc::Sprite::layer() and palette() member functions * Add doc::Layer::cel() member function * Add doc::Palette::entry() member function() * Add doc::frame_t type * Move create_palette_from_rgb/convert_pixel_format to render library * ExportSpriteSheet doesn't need a temporary image now that we can specify the source rectangle in the render routine
