Custom fill pattern are read top/bottom flipped from .lyp files

[klayoutmatthias]

The effect is this: define a fill pattern in the custom fill pattern area. Pick a pattern which is not symmetric in Y (e.g. a letter "A"). Save the layer properties and load again. Effect: the pattern is flipped and the "A" is bottom-up. Save and load again to revert the effect.

Apparently the .lyp reader flips the pattern.

Here is a testcase: load 225.gds with 225.lyp...

225.zip

So the problem can be fixed in two places:

• In the .lyp reader: this means all existing files from 0.24.x become valid again. But all files tweaked to fit to 0.25.x become flipped.
• in the .lyp writer: this means all files tweaked for 0.25 stay valid. Old files need to be adapted.

So either solution means, someone will blame me ...

But here is my decision: the first one to complain was using old files he wanted to be correct again. So I'll fix the issue in the READER. Sorry for the others.
