CVSROOT: /sources/gnash
Module name: gnash
Changes by: Zou Lunkai <zoulunkai> 08/06/05 03:26:33
Modified files:
. : ChangeLog
backend : render_handler_agg.cpp
render_handler_agg_style.h
render_handler_cairo.cpp render_handler_ogl.cpp
gui : gui.cpp
libbase : utility.h
server : edit_text_character.cpp matrix.cpp matrix.h
sprite_instance.cpp
testsuite/actionscript.all: TextField.as
testsuite/server: MatrixTest.cpp
Log message:
* server/matrix.{h,cpp}: code refactory, use integer math for
swf matrix,
which would be more compatible later.
* libbase/utility.h: add a Fixed16Mul() for fixed point
multiplication.
* server/edit_text_character.cpp, sprite_instance.cpp,
gui/gui.cpp,
backend/render_handler_agg.cpp
backend/render_handler_agg_style.h
backend/render_handler_cairo.cpp
backend/render_handler_ogl.cpp: synchronize the new matrix
interfaces.
* testsuite/server/MatrixTest.cpp: disable the tests
temporarily, which are
too accurate for the new matrix.
* testsuite/actionscript.all/TextField.as: accept an accuracy
lost temporarily.
