- Drop addon is based on WM_DROPFILES, dragdrop addon is based on the OLE IDragDrop interface and thus can registerer more interactions.
- The allg5ui implementation will try to fall back on the drop addon (because the dragdrop addon wouldn't work properly).
- Drop addon is refactored to use the same interface as the dragdrop addon.
Refactored Size (on Renderer) to return geom.Point instead of geom.PointF32.
Refactored Width and Height (on Texture) to return int instead of float32.
Refactored texture dimensions to be represented by ints instead of float32s.
