Re: vbscript: Added support for more builtin constants

Hi, While running your changed tests on Windows, I think I found new failures. Being a bot and all I'm not very good at pattern recognition, so I might be wrong, but could you please double-check?

See http://msdn.microsoft.com/en-us/library/windows/desktop/dd318144%28v=vs.85%… And it need tests of course.

Re: gdiplus: fix rounding error (?)
by Vincent Povirk 29 Oct '12

29 Oct '12

That was the worst possible defence of this patch, but I think it should be included. What it's actually doing is removing the duplicated logic between the earlier bit of GdipDrawString, where out-of-range sizes are set to 1 << 23, and this if statement where we only apply a clipping rectangle if the sizes are out of range. We could also have added a check for e.g. scaled_rect.Width >= INT_MAX here, but I think it's better that we don't duplicate the logic.

You may kill that too while you change those lines. Cheers Rico
