4:30 a.m.
* utils/Python/xmlgenerator.py: This extends graphics element for spice
XML composing, and support sub-elements settings for audio, images,
streaming and so on:
<graphics type='spice' autoport='yes'>
<image compression='auto_glz'/>
<jpeg compression='auto'/>
<zlib compression='auto'/>
<playback compression='on'/>
<streaming mode='filter'/>
<clipboard copypaste='no'/>
</graphics>
* utils/Python/xmlbuilder.py: Add 2 methods add_graphics() and
build_graphics() to XmlBuilder class.
