2005-10-19  David Schleef  <[e-mail]>

2005-10-19  Eric Anholt  <[e-mail]>

	* libswfdec/actions_tags.c: (action_extends):
	Throw together a slightly less stubbed ActionExtends.  May still have
	issues with the constructor getting hooked up.

2005-10-17  David Schleef  <[e-mail]>

	* plugin/plugin.c: Update message.

2005-10-16  Eric Anholt  <[e-mail]>

	* libswfdec/swfdec_object.c:
	* libswfdec/swfdec_shape.c:
	* libswfdec/swfdec_sound.c:
	Minor cleanups exposed by sparse: mark several things static, add
	a prototype for another, and add descriptions for some MB actions.  Fix
	a broken include path that sparse choked on.

2005-10-16  Eric Anholt  <[e-mail]>

	* libswfdec/actions_tags.c: (action_push):
	Fix a memory leak in string pushes.

2005-10-10  David Schleef  <[e-mail]>

	* libswfdec/jpeg/huffman.c: (huffman_table_decode_macroblock):
	* libswfdec/jpeg/jpeg.c: (generate_code_table):
	* libswfdec/jpeg/jpeg_debug.h: Turn off JPEG debugging.

2005-08-29  Eric Anholt  <[e-mail]>

	* libswfdec/actions_builtin.c: (movieclip_new):
	Fix another GC breakage in movieclip rooting.  Roots are added as
	pointers to gc-things (where a gc-thing is a pointer to a JS_object,
	jdouble, etc.).  However, the pointer-to-gcthing must remain valid until
	JS_RemoveRoot, while we were passing a pointer to a stack variable.
	Many thanks to Brendan Eich (spidermonkey developer) for giving me the
	pointer on how to fix it.

2005-08-29  Eric Anholt  <[e-mail]>

	* libswfdec/actions.c: (swfdec_init_context):
	* libswfdec/actions_builtin.c: (action_register_sprite_seg):
	* libswfdec/swfdec_actions.h:
	Expand the scope of GC debugging, exposing a new issue quickly.

2005-08-29  Eric Anholt  <[e-mail]>

	* libswfdec/actions_builtin.c: (swfdec_init_context_builtins):
	Don't forget to initialize the jsval when setting _root.  Fixes a GC
	crash, at a minimum.

2005-08-27  Eric Anholt  <[e-mail]>

	* libswfdec/actions.c: (swfdec_init_context), (action_script_call),
	(swfdec_action_script_execute), (stack_push):
	* libswfdec/actions_builtin.c: (movieclip_new):
	* libswfdec/actions_tags.c: (stack_pop_to_string),
	(stack_pop_to_object), (stack_pop_to_number), (stack_pop_to_int32),
	(stack_pop_to_bool), (action_alloc_stack_argv),

	(action_to_string), (action_add_2), (action_less_2),
	(action_unary_op), (action_string_greater), (action_extends):
	Improve GC-safety of actionscript code by being more careful with
	storage of short-lived values and results of conversions.  Also corrects
	some misuse of the result of JS_ValueToNumber, improves error checking,
	and fixes JS_AddRoot arguments.  Finally, a define is added to allow for
	forcing frequent GCing, which exposes that we've got issues (still).

2005-08-17  David Schleef  <[e-mail]>

	* libswfdec/swfdec_bits.c: (swfdec_bits_syncbits): disable the
	endpoint checking, because it's not important here.
	* libswfdec/swfdec_render.c: (swfdec_render_iterate): change
	errors into debugging
	* libswfdec/swfdec_render_cairo.c: (swfdec_shape_render): handle
	button mapping in cairo backend, the same crappy way we do
	with libart.

	(swfdec_bits_get_be_u16), (swfdec_bits_get_u32),
	(swfdec_bits_syncbits): Check validity of pointers.
	* libswfdec/swfdec_button.c: (swfdec_button_execute): execute
	code at the end of a frame.
	* libswfdec/swfdec_decoder.h: same
	* libswfdec/swfdec_render.c: (swfdec_render_iterate): same
	* libswfdec/swfdec_sprite.c: (swfdec_sprite_render_iterate): same
	* libswfdec/swfdec_sprite.h: same
	* libswfdec/swfdec_render_cairo.c: (swfdec_shape_render): set
	pattern extension correctly.
	* libswfdec/swfdec_shape.c: (swf_shape_add_styles),
	(swf_morphshape_add_styles): remove mysterious factor, because it's
	not necessary with cairo.
	* libswfdec/swfdec_text.c: (define_text): more checking.

2005-06-28  David Schleef  <[e-mail]>

	* configure.ac: Make cairo backend default, because I like it.
	* libswfdec/swfdec_audio.c: (swfdec_audio_render): remove debugging
	* libswfdec/swfdec_render_cairo.c: (swfdec_matrix_to_cairo),

2005-06-16  Eric Anholt  <[e-mail]>

	* libswfdec/swf.c:
	* libswfdec/tags.h:
	Document a couple more tag names.  Couldn't find what MX4 is.

2005-06-16  Eric Anholt  <[e-mail]>

	* libswfdec/swfdec_shape.c: (swf_shape_add_styles),
	(swfdec_shape_compose):
	Add support for fill style type 0x42 and 0x43, the unsmoothed versions
	of the previous two fill styles.  Actually, the previous two are
	unsmoothed in our current implementation.  Also, attempt to support
	repeating fill styles, though I don't have a good test for them.
