sdl2_frt/test/testdropfile.c
Ryan C. Gordon 8e855f2fbc Added SDL_DROPBEGIN and SDL_DROPCOMPLETE events, plus window IDs for drops.
This allows an app to know when a set of drops are coming in a grouping of
some sort (for example, a user selected multiple files and dropped them all
on the window with a single drag), and when that set is complete.

This also adds a window ID to the drop events, so the app can determine to
which window a given drop was delivered. For application-level drops (for
example, you launched an app by dropping a file on its icon), the window ID
will be zero.
