New Revision: 1298

Modified:
   trunk/MgDev/Common/Stylization/GDRenderer.cpp
Log:
Changed output PNG encoding from interlaced to non-interlaced. Supposedly it is faster to encode non-interlaced PNGs, and this is also confirmed by some measurements I made. PNG compression being extremely slow, every little bit helps.

Modified: trunk/MgDev/Common/Stylization/GDRenderer.cpp
