Hi all,
I'm asking if I can backport my modifications related to the WMSTileFuser
on the 1.5.x branch of GeoWebCache.
NOTE: The pull request will upgrade the ImageIO-Ext version.
I will be pleased to answer to your questions.
Cheers,
Nicola.

>> - Geotools: 11.x and 10.x

>> https://jira.codehaus.org/browse/GEOS-6376.
>> - for GepServer I have moved the Quantizer code to GeoTools and the
>> PNGEncoder code to ImageIO-Ext. (see the JIRA above).
>> - for GeoWebCache, I have improved the WMSTileFuser class and made
>> full WMS support configurable from the geowebcache.xml file. Also I added
>> a
>> new WMS parameter called "hints" which can be set to *SPEED*,
>> *DEFAULT* and *QUALITY.* This parameter gives the possibility to make
>> a WMS request faster or with a better quality.
