Simple VDub Filters

Since it's necessary that it be loaded after vdub_filters.avsi, it might be best to leave it out of the plugins (autoloading) directory.

# Zoom by Donald Graft and Avery Lee, v1.2                                                          #

# What this adjusted version does is the following:                                                 #
# Given the focus point (focusX,focusY) it makes a smaller clip (with size: (2*(w-focusX),2*focusY) #
# including black boundaries to get the original resolution) starting when zooming in and ending    #
# after zooming out. Starting at frame "start_frame" is zooms in to "perc" percent at "end_frame"   #
# and zooms out again starting at frame "start2_frame" and ending at frame "end2_frame".            #
#                                                                                                   #
# The width and heigth of the original clip needs to be even.                                       #
# mode = "neighbour", "bilinear", "bicubic", "p_bilinear" or "p_bicubic."                           #
