-// A class designed to help with WM_PAINT operations on Windows. It will create
-// the bitmap and canvas with the correct size and transform for the dirty rect.
-// The bitmap will be automatically painted to the screen on destruction.
-//
-// You MUST call isEmpty before painting to determine if anything needs
-// painting. Sometimes the dirty rect can actually be empty, and this makes
-// the bitmap functions we call unhappy. The caller should not paint in this
-// case.
-//
-// Therefore, all you need to do is:
-//   case WM_PAINT: {
-//     PAINTSTRUCT ps;
-//     HDC hdc = BeginPaint(hwnd, &ps);
-//     gfx::CanvasSkiaPaint canvas(hwnd, hdc, ps);
-//     if (!canvas.isEmpty()) {
-//       ... paint to the canvas ...
-//     }
-//     EndPaint(hwnd, &ps);
-//     return 0;
-//   }
-// Note: The created context is always inialized to (0, 0, 0, 0).
