The options are now:
-duration d -> set the whole animation to duration 'd'
-duration d,s -> set only frame 's' to duration 'd'
-duration d,s,e -> set only interval [s,d] to duration 'd'
+ style fix

this will force a constant duration for an interval of frames
in an animation.
Notes:
a) '-duration [...]' can be repeated as many times as needed.
b) intervals are taken into account in option order. If they overlap, values will be overwritten.
c) 'start' and 'end' can be omitted, but not the duration value.
d) 'end' can be equal to '0', in which case it means 'last frame'
e) single-image files are untouched (ie. not turned into an animation file).
Some example usage:
webpmux -duration 150 in.webp -o out.webp
webpmux -duration 33,10,0 in.webp -o out.webp
webpmux -duration 200,2 -duration 150,0,50 in.webp -o out.webp

from man-pages (7):
provides a comma-separated list of related man pages, ordered by section
number and then alphabetically by name, possibly followed by other
related pages or documents. Do not terminate this with a period.

this enables webpmux to accept input files starting with '-' when using
-get/-set/-strip; -info & -frame expect an input file as one of their
parameters so no changes are necessary there.

Now, its: +duration+xoffset+yoffset+disposal
+disposal can be omitted and will default to +0 (NONE)
additionally, +xoffset+yoffset can be omitted and will default to +0+0

- Allow a duration of 0
- Rename LOOP chunk to ANIM and add the background color field to it.
- Add a disposal method field for each animation frame.
- Modify webpmux.c binary interface to allow the input of background color
and disposal methods. Also make '-loop' and '-bgcolor' arguments optional
with some default values.

- Also, use the term 'fragments' instead of 'tiling' in code
- This makes code consistent with the spec.

Use separate fourCCs "XMP " and "EXIF" instead of a common "META"
Also, some refactorization in webpmux.c
Change-Id: Iad3337e5c1b81e785c60670ce28b1f536dd7ee31
- send errors to stderr
- send help to stdout
- add image size to webpmux -info output and send to stdout
- correct webpmux exit values
