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.
