Subject: Reverted most of vfbScreenInfo to the original RealVNC implementation,
X-Git-Tag: v0.0.90~384^2~607
X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=d6a2914fc2208d6ab3562113af6a306c9bc00000;p=tigervnc.git

Reverted most of vfbScreenInfo to the original RealVNC implementation,
since miSetVisualTypesAndMasks breaks "xwd", for some reason.
