(x_reply_selection_request): Put x_uncatch_errors in an unwind.
(Fx_get_atom_name): Call x_uncatch_errors earlier.
* window.c (Qscroll_up, Qscroll_down): New syms.
(window_scroll_pixel_based): Make preserve_y static to avoid
getting point stuck when scrolling 1 line.
(x_uncatch_errors): Unused count argument deleted.
* xterm.c (x_catch_errors): Don't use record_unwind_protect, since
it can be called in a signal handler.
(x_catch_errors_unwind): Function deleted.
(x_uncatch_errors): Deallocate last x_error_message_stack struct.
(x_check_errors): Call x_uncatch_errors before signalling error.
(x_load_font, x_term_init, XTmouse_position, handle_one_xevent)
(x_connection_closed, x_list_fonts): Use new versions of
x_catch_errors and x_uncatch_errors.
* xselect.c (x_own_selection, x_decline_selection_request)
(x_reply_selection_request, x_get_foreign_selection)
(Fx_get_atom_name, Fx_send_client_event): Likewise.
* xfns.c (x_real_positions, x_set_mouse_color, Fx_focus_frame):
Likewise.
* eval.c (record_unwind_protect): Add an assertion.
type == XA_ATOM, data contains array of int, not array of Atom.
(x_property_data_to_lisp, selection_data_to_lisp_data): Comment
update: data must be array of int for format == 32.
XChangeProperty so that 64 bit longs are handeled correctly.
(x_get_window_property): If format is 32 and long is bigger than 32
bits convert data from XGetWindowProperty from long array to int array.
(lisp_data_to_selection_data): When the input is a vector and the
format is 32, allocate a long array even if long is bigger than 32 bits.
(x_fill_property_data): Use char, short and long as the man page
for XChangeProperty specifies. This way the data returned is OK for
both 32 and 64 bit machines.
(x_handle_dnd_message): Calculate size correctly even for 64 bit
machines.
(Fx_send_client_event): Undo change from 2005-02-05,
x_fill_property_data now handles that case.
(xg_tool_bar_callback, xg_tool_bar_help_callback)
(update_frame_tool_bar): Cast to EMACS_INT to avoid compiler
warning.
* xselect.c (x_get_foreign_selection, x_fill_property_data)
(Fx_get_atom_name, Fx_send_client_event): Replace XFLOAT with
XFLOAT_DATA to get extract number from Lisp object.
(x_queue_selection_requests, x_queue_event)
(x_start_queuing_selection_requests)
(x_stop_queuing_selection_requests): Add new queue for selection
input events to replace previous XEvent queue in xterm.c.
(queue_selection_requests_unwind): Adapt to new queue.
(x_reply_selection_request): Adapt to new queue. Unexpect
wait_object in case of x errors (memory leak).
(x_handle_selection_request, x_handle_selection_clear): Make static.
(x_handle_selection_event): New function. May queue selection events.
(wait_for_property_change_unwind): Use save_value instead of cons.
Clear property_change_reply_object.
(wait_for_property_change): Abort if already waiting.
Use save_value instead of cons for unwind data.
(x_handle_property_notify): Skip events already arrived, but don't
free them, as "arrived" field is checked by wait_for_property_change,
and it will be freed by unwind or explicit unexpect_property_change.
(x_get_foreign_selection): Add to new queue.
(receive_incremental_selection): Don't unexpect wait_object when done
as it has already been freed by previous wait_for_property_change.
(x_check_property_data, x_fill_property_data)
(x_property_data_to_lisp, mouse_position_for_drop)
(Fx_get_atom_name, x_handle_dnd_message): New functions for DND support.
(Fx_send_client_event): Moved here from xfns.c.
(syms_of_xselect): Add Sx_get_atom_name and Sx_send_client_message.
(Qforeign_selection): New variable.
(syms_of_xselect): Intern and static it.
(selection_data_to_lisp_data): Return a unibyte string made from
data with `foreign-selection' text property.
(symbol_to_x_atom): Pay attention to QUTF8_STRING.
(x_atom_to_symbol): Likewise.
(x_get_local_selection): New argument local_request. If it is
nonzero, call handler_fn with the second arg nil.
(x_handle_selection_request): Call x_get_local_selection with
local_request 0.
(lisp_data_to_selection_data): Don't encode the string here.
(Fx_get_selection_internal): Call x_get_local_selection with
local_request 1.
(syms_of_xselect): Intern and staticpro QUTF8_STRING.
