gtk/gdk/linux-fb/gdkgeometry-fb.c
Alexander Larsson 1c805555ce Huge GtkFB patch with lots of small bugfixes and initial selections implementation.
2000-11-23  Alexander Larsson  <alexl@redhat.com>

	* gdk/linux-fb/gdkselection-fb.c:
	Initial selection implementation.

	* gtk/gtkselection.c:
	if GDK_WINDOWING_FB defined, include linux-fb/gdkfb.h and look up
	requestor in gtk_selection_request.

	* gdk/linux-fb/gdkfb.h, gdk/linux-fb/gdkglobals-fb.c:
	Added gdk_selection_property atom.

	* gdk/linux-fb/gdkprivate-fb.h:
	Export _gdk_selection_window_destroyed.
	Removed mask_off_x/y from GdkCursorPrivateFB.
	Removed hbearing, added top, left to PangoFBGlyphInfo.

	* gdk/linux-fb/gdkwindow-fb.c (_gdk_windowing_window_destroy):
	Call _gdk_selection_window_destroyed
	(_gdk_windowing_window_init): Don't call gdk_cursor_new() before
	the root window has been created.
	(static_dx_hack, static_dy_hack, compare_draw_rects,
	gdk_fb_window_move_resize): Remove unnecessary sort of rectangles
	in region. They are already sorted. Instead just traverse them in
	reverse if draw_direction < 0.

	* gdk/linux-fb/gdkinput-ps2.c (send_button_event):
	Double-clicks must be sent after the normal button_press.
	(gdk_fb_cursor_unhide): Remove usage of mask_off_x/y. Clean up.

	* gdk/linux-fb/gdkgeometry-fb.c (gdk_window_scroll):
	Pass _gdk_fb_screen_gc instead of NULL.

	* gdk/linux-fb/gdkmain-fb.c (_gdk_windowing_init_check):
	Initialize gdk_selection_property.
	(gdk_event_make): Remove unused code.

	* gdk/linux-fb/gdkcursor-fb.c:
	Make the pixmap for the cursor the same size as the mask. Also remove
	the mask_off_x/y fields in GdkCursorPrivateFB and combine
	_gdk_cursor_new_from_pixmap() and gdk_cursor_new_from_pixmap()
	Now the whole cursor is visible.

	* gdk/linux-fb/gdkdrawable-fb2.c (gdk_fb_draw_drawable_3):
	Fix bug where xdest+height instead of ydest+height was used
	to calculate if the source and dest overlapped. This fixes the
	redraw bug when the main window in testgtk was scrolled when
	partially covered by a tall window.
	Copy rectangles in region in order depending on draw_direction.
	Also moved the draw_direction flipping of start_y and end_y into
	the gc functions, as this might not be what all of them want.
	(gdk_fb_draw_lines): Support dashed lines.
	(gdk_fb_draw_glyphs): Clean up glyph placement. Also fix positioning
	so that the text is positioned correctly (was 1 pixel high).

	gdk/linux-fb/gdkgc-fb.c:
	Initialize cap_style to GTK_CAP_BUTT. This fixes a problem where
	all lines were drawn a pixel to short. Also checked the default of
	the rest of the values, and they're the same as X now.

	* gdk/linux-fb/gdkpango-fb.c (pango_fb_font_get_glyph_info):
	Clean up pixel positioning of the glyphs. Just use bgy->top and
	bgy->left. Also used PANGO_PIXEL where appropriate and added 0.5
	to all divisions to get correct rounding behaviour.

	* gdk/linux-fb/gdkrender-fb.c (gdk_fb_draw_drawable_generic,
	gdk_fb_draw_drawable_memmove, gdk_fb_draw_drawable_aa_24):
	Moved start_y/end_y flip into draw_drawable implementations.
	Flip also x rendering when draw_direction < 0.
	Remove unneccesary multiply with draw_direction.
