hi all,      I'm reading cairo's source these days. I found these two macros are used heavily in cairo-ft-font.c. They're 64-bit division, generally speaking, they're slow. I wonder if we change these two macros to something that directly handling the IEEE double, will be noticable faster?    PS. According to Jinghua Luo, this is discuessed before. I'm sorry to raise it again because I couldn't find the archives. Best Regards, Mai.
