GRAPHICS PERFORMANCE

Windows users experiencing graphical issues can edit the photogrok.bat
file in the platform neutral release to add the following parameter:

-Dsun.java2d.d3d=false

This can be inserted just before the "-cp" in the "start javaw" lines.
This flag is already set in the Windows-specific release.

Users on all platforms can experiment with the following flag to use
Java's opengl graphics pipeline for better performance. This typically
requires the latest graphics drivers. Remove the flag if you
experience issues:

-Dsun.java2d.opengl=true 



MEMORY USE

The Windows and OS X releases are set to use a maximum of 2gb of memory.
This can be changed in the platform neutral release by editing
either photogrok.bat for Windows or the photogrok bash script for both
Linux and Mac. Change the max amount of memory by editing the 
-Xmx1024m parameter. To use 2GB, change to -Xmx2048m.

Increasing memory can improve performance for users displaying a very
large number of thumbnails or high megapixel images.
