	* io-tga.c (pixbuf_flip_row):
	(pixbuf_flip_vertically): Auxiliary functions used to implement
	support for arbitrary origins.
	(parse_data_for_row_pseudocolor):
	(parse_data_for_row_truecolor):
	(parse_data_for_row_grayscale):
	(parse_data_for_row):
	(fill_in_context): Remove the check for upper-left origin.
	(parse_rle_data): Support arbitrary origins. (#105912)

	* io-tga.c (fread_check):
	(fseek_check):
	(get_header_from_file):
	(get_colormap_from_file):
	(get_image_pseudocolor):
	(swap_channels_pixbuf):
	(get_image_truecolor):
	(get_image_grayscale):
	(gdk_pixbuf__tga_load): Remove the non-incremental load
	implementation, since we have generic_image_load () now.

	(gdk_pixbuf__tga_stop_load): Fix a potential crash discovered by
	pixbuf-lowmem.
