 Changes in 1.8 (??.??.2011)
 
+ - Add some getters to IGUIImage: getImage, getColor
+
  - API change: Added write only lock mode for textures. The lock method has changed the signature and uses an enum parameter now instead of a bool. The default is still to lock for read/write (previously 'false'). The old 'true' value should be replaced by ETLM_READ_ONLY.
 
  - Speedup deleting of particles
