[Ohrrpgce] [ohrrpgce/ohrrpgce] 64-bit SDL 1.2 Mac builds show black screen when fullscreened (#1138)

[James Paige]

I updated SDL2 to 2.0.12
SDL1.2 was already present at 1.2.15 but I went ahead and re-downloaded and
reinstalled.

Both frameworks were previously present in both /Library/Frameworks and in
~/Library/Frameworks so I completely removed the ~ versions, now they are
only in one place, and are current to the best of my knowledge

I don't know if they were 32 bit or 64 bit. I couldn't tell.

I forced an early Mac nightly build, and I think I worked
