| 754 | * For example in Google Map api test case, it takes Dream device at least |
| 755 | * 150ms to do a full cycle in the WebViewCore by processing a touch event, |
| 756 | * triggering the layout and drawing the picture. While the same process |
| 757 | * takes 60+ms on the current high speed device. If we make |
| 758 | * TOUCH_SENT_INTERVAL too small, there will be multiple touch events sent |
| 759 | * to WebViewCore queue and the real layout and draw events will be pushed |
| 760 | * to further, which slows down the refresh rate. Choose 50 to favor the |
| 761 | * current high speed devices. For Dream like devices, 100 is a better |
| 762 | * choice. Maybe make this in the buildspec later. |
| 763 | * (Update 12/14/2010: changed to 0 since current device should be able to |
| 764 | * handle the raw events and Map team voted to have the raw events too. |
