Qt6 Migration + libjepeg 9F

[davidagnome]

How feasible is migrating to Qt6 and libjpeg 9F?

From my understanding, there should be improve performance with Metal and MacOS as well as on Vulkan for other platforms. Are any modules wholly incompatible or have no equivalent?

Qt6 must be possible. Qt5 is preferred because Qt6 requires windows10+.

Idk what's up with libjpeg 9F, doesn't build just pick w/e available libjpeg?
