[mapguide-internals] MapGuide 2.3 and FOSS4G 2011

Fri Jun 10 23:53:40 EDT 2011

two small server fixes which would be really good for 2.2.1 are

AGG Renderer does not properly handle transparency for non-PNG image formats
http://trac.osgeo.org/mapguide/ticket/743 (affects MGE as well)

MAPAGENT call crashes webservers (IIS & Apache)
http://trac.osgeo.org/mapguide/ticket/1705  (fix identified, just
needs a code review/tweak)

for Fusion,

there is a mega patchset which Ennoble has developed which addresses
a lot of performance issues, legend issues, nigglying bugs and proper support
for multiple maps. IE less than v9 still sucks, but it works reliably.

Complex multi-maps load in 4s in FF4 and 10s in IE8 without locking up
the browser!!

Merge github fork changes back to fusion repo
http://trac.osgeo.org/fusion/ticket/460

The IE9 fixes have already been committed to trunk and just need to be
back ported
