* Remove clipdrop->dnd_target_state, it's not used anymore * Remove non-functioning _gdk_dropfiles_store(), store dropfiles list in GdkWin32Drop instead * Fix multiple comment typos * Fix _gdk_win32_get_clipboard_format_name_as_interned_mimetype() to leave names that look like mime/types alone * Refactor _gdk_win32_add_w32format_to_pairs() to populate GdkContentFormatsBuilder directly, instead of making a GList * Rename context -> drag (still using GdkDragContext type, but [almost?] all variables and comments say "drag" now) * Rename GdkDropContext -> GdkDrop * Rename some parameter names for clarity * Rewrite local protocol to look more like OLE2 protocol instead of mirroring the structure of the X11 API. * Add handle_events field to GdkWin32DragContext, to shut off event handling (temporary fix until GTK is patched up) * Remove _gdk_win32_drag_context_find() - the drag object is stored in GdkDrop instead. Use _gdk_win32_find_drag_for_dest_surface() to get it initially. * Remove target_ctx_for_window, droptarget context is stored in the surface instead. * Call gdk_drag_context_set_cursor() just like wayland backend does (slightly broken for now) * Clean up the action choosing code (filter source actions by using keyboard state, pass that to GTK, get all actions supported by GTK in response, match them up with filtered source actions, return the result, falling back to COPY in case of multiple actions) * Check drag_win32->protocol instead of the use_ole2_dnd variable where possible * Remove protocol checks from functions that are only used by the local protocol * Use event state to manufacture the keyboard state for WM_MOUSEMOVE * Change function names printed by GDK_NOTE to name the actual functions, not their theoretical generic GDK stack ancestors * Consistently use drag_win32 and drop_win32 variables instead of a mix of that and win32_drag/win32_drop * Return FALSE from button handler to ensure that GTK gets the button event to break implicit grab * Emit leave event on failed idroptarget_drop() calls
