2005/01/25 23:22:42 thb 1.3.10.2: #i36950# More text output fixes: basegfx obviously does not prune exactly identical polygons into one, which might lead to errorneously empty clips. Fixed symptomatically by falling back to rect clipping for some common cases. Added handling of StretchText meta action 2005/01/22 00:51:02 thb 1.3.10.1: #i36950# Handling push/pop of OutDevState correctly; respect the fact that RenderState's clip is also subject to RenderState transform, thus, when translating an action, have to translate back clip before!
