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

[Ralph Versteegen]

James, could you please upgrade the (system installed) SDL.framework on the
Mac build machine to 1.2.15 to try to fix this bug?
Oh, I just remembered... actually, the SDL devs have declared they will no
longer provide builds for SDL 1.2, even though SDL 1.2.16 was declared late
last year, with a huge number of bugfixes. So really we should upgrade to
that instead, but I'll have to compile it myself. I won't get around to
that for at least a couple weeks. Up to you whether you want to wait.

Though I find it strange that it would have such an ancient version of SDL
1.2 installed (mac/get_sdl_frameworks.sh downloads 1.2.15); it makes me
wonder whether the SDL devs just forgot to update the version number in the
framework. They're really bad with documenting their releases - they don't
note release dates anywhere and didn't write down the changelog for SDL
1.2.15 (2011) until 2019!
If you're upgrading SDL 1.2, could you upgrade the SDL2 framework to 2.0.12
too? It has several new features I'll probably end up using, especially
SDL_BLENDMODE_MUL.
