In essence, it was always this big, just you never saw it
because it got downloaded during the installation process.
It was also significantly bigger before because the download it
did was the >30MB dmd zip that contained files for all platform,
not just Windows. The installer is LZMA compressed too so it's
even smaller than the dmd windows-only zip (16MB).
Because of this, download size is now 1/3rd what it was and
installation size dropped from 176 MB to just 71 MB.
