// Name: rd_GuessWhat
// Version: 3.0
// 
// Description:
// This script displays a palette with controls for guessing the
// alpha mode and/or pulldown of the selected footage items. Basically,
// a batch mode for these operations.
// 
// If a proxy is active for a footage item, the operation will be
// applied to the proxy, not the main footage.
// 
// Note: After the operation finishes, the info appearing next to the
// selected footage item in the Project panel might not update to
// reflect the guessed setting, so deselect and then reselect it to
// view the current setting.
// 
// Note: This version of the script requires After Effects CS3 
// or later. It can be used as a dockable panel by placing the 
// script in a ScriptUI Panels subfolder of the Scripts folder, 
// and then choosing this script from the Window menu.
// 
// Originally requested by Matt Silverman.
// 
// Legal stuff:
// This script is provided "as is," without warranty of any kind, expressed
// or implied. In no event shall the author be held liable for any damages 
// arising in any way from the use of this script.
// 
// In other words, I'm just trying to share knowledge with and help out my
// fellow AE script heads, so don't blame me if my code doesn't rate. :-)
