bug for 'lock aspect ratio'

[Kevlar]

This bug, alas, affects not only Lubuntu (Bug 943269) but all distributions ; how to reproduct it :
1- draw anything (box, ellipse) with 'aspect ratio' locked (<CTRL> key)
2- release 'aspect ratio' key
3- select the newly drawed object, and by clicking, switch to "resizing mode".
4- hit the <CTRL> key to activate "aspect ratio locked", and resize ;
You will see 2 things :
1- the aspect raio isn't work for the object, only for the bounding box around the object
2- the bounding box isn't correctly computed.

after additionnal tests, this bug is specific for "ellipses" objects (during resizing, we have negative radius computed !)

[Louis Moureaux (louis-m-deactivatedaccount)]

This bug seems to appear randomly when resizing to a smaller then a larger size, with both rectangles and ellipses. Resulting shape can be larger or smaller than needed. I've never had this bug with horizontal size, only vertical size is wrong.

Found a fix : the bug is produced by GooCanvas function like this :
" g_object_get(item,"center_x",&cx,"center_y",&cy,"radius_x",&rx,"radius_y",&ry,NULL); "

We get NEGATIVE values for ry ! (i.e. the ellipse's radius for y coordinates)

So I've added some code to get only POSITIVE radius.

fixed, in revision #101, released
