Fix critical PNG save bug if colors must be counted
Change minimum resize width/height to 1/1
New dedicated "Resize" option in Batch Wizard

Very cool feature, IMO, and long-requested by multiple users.

One of the most common uses of a batch convert tool is to resize a bunch
of images.  Unfortunately, PhotoDemon previously required the user to
create a specific resize macro if they wanted to do this.

But no more!  Right on the batch wizard is an option to "resize image".
*This can be used in conjunction with a macro*.  They are not mutually
exclusive, meaning you can apply both a resize and a separate macro to
every image in a batch conversion.

A few additional resize-related items have been added for convenience:

1) The default resize width/height are automatically set to the current
screen resolution.
2) Like the stock resize dialog, aspect ratio is dynamically displayed
3) Like the stock resize dialog, three resize options are provided:
stretch-to-fit, fit inclusively (with potential borders), fit
exclusively (with potential cropping).  As a nice bonus, I've added a
sample image that displays what the various resize options do.
4) No resample box is provided.  This cluttered up the form too much,
and really serves no purpose.  Advanced users can create their own
custom resize macro if they want to fiddle with resampling algorithms.
At present, batch resizing will default to the highest-quality
general-purposes resample algorithm (3-lobe Lanczos).
5) A number of descriptions in the wizard have been rewritten to match
this new functionality.  The wizard specifically points out that if
multiple photo editing actions are selected, they will be applied in the
order they appear on-screen.
