uicollectionview's Issues

Use SetWindowsOrgEx to optimize scrolling experience

When scroll the content view, as item's size wasn't changed, there is no need to frequently update item's layout (SetPos). This can be optimized by putting all items at (0, 0), and let content view to manage their positions, when repainting is required, use SetWindowsOrgEx to offset the paint origin, and then paint item into correct rectangle directly.

Disadvantage: we won't manage the position of sub items anymore, thus HITTEST by mouse point will not work in the content view. Also, any interactive elements (buttons, etc.) in the sub items may not function as well.
