frame time? do you mean frame conversion time?

[dtapuska, 2016/12/01 16:26:43]

Ya this comment needs some work. I mean that when we convert at the web layer.
Applying the root frame to the translations.

+  float frameTranslateX;  // post scale translation x value.
+  float frameTranslateY;  // post scale translation y value.

[majidvp, 2016/12/01 15:46:31]

should frameTranslateX and frameTranslateY just be a WebFloatPoint?

[dtapuska, 2016/12/01 16:26:43]

WebFloatPoint isn't packed. So I might be able to pack it and see if it doesn't
increase the size of the struct. But good idea.

 
   // Returns true if the WebInputEvent |type| is a mouse event.
   static bool isMouseEventType(int type) {
     return MouseTypeFirst <= type && type <= MouseTypeLast;
   }
 
   // Returns true if the WebInputEvent |type| is a keyboard event.
   static bool isKeyboardEventType(int type) {
     return KeyboardTypeFirst <= type && type <= KeyboardTypeLast;
   }
