Subject: Added PlayerOptions::setPF(). This function calculates all PixelFormat
X-Git-Tag: v0.0.90~384^2~587
X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=7b1ebaea1467d981af59d0aff5429662f810b8fa;p=tigervnc.git

Added PlayerOptions::setPF(). This function calculates all PixelFormat
struct properties by rgb order, rm, gm, bm.
