-// 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). |
