2017-09-08Fix one-second spin in fx_random.cppTom Sepez
Take seed generation logic from base's address_space_randomization.cc. One small tweak is to avoid the bottom three bits of a stack address and invert, to make leaking ASLR more difficult along the lines of the freelist masking in base's partition allocator. Another tweak is to mix in some more time-based information. Another tweak is to add in the times called so that rapid successive calls return different results.

2017-09-08Move decompressing of JPX out of Init and into DecodeRyan Harrison
In the existing implementation of the JPX decoder, Init extracts the header from the image and then immediately decompresses it. This is problematic if it is a very large image that we won't be able to allocate a bitmap for. The code has been changed to instead delay decompression until the Decode method, since things like dest Bitmap generation can be performed using just the header information. There is also a bit of renaming/casting cleanup, because I was having a hard time parsing what was a local vs member variable.

2017-09-01Cleanup usages of Mid(foo, 1), Right(1), and Left(1)chromium/3203Ryan Harrison
Mid(foo, 1) is equivalent to [foo], if all you want is the character. Similarly Left(1) is [0]. It is faster also, since it does not need to create intermediate strings. Right(1) is a touch more tricky, since it requires something like GetLength() ? [GetLength() - 1] : 0;. A new method, Last() has been added to perform this character extraction. Multiple call sites have been updated to use more efficient/simpler syntax. There are a number of call sites that use on these patterns, but based on the surrounding context we actually need/want a string, so they have not been modified.
