Werner et al.,
What is the Freetype policy and/or goals with regard to integer overflows?
How practical are the large sizes that push outline dimensions beyond 16
bits, or pixel size of 1024? In a few places I see 64-bit arithmetic
utilized to control the overflow by means of FT_Int64. This
What is the Freetype policy and/or goals with regard to integer
overflows?
Overflows should be avoided. If you need an exact bit width, use
FT_Int{16,32}. 64bit variables are nowhere used except in code
guarded with FT_LONG64 (however, the code should be written so that it
works with FT_Int
