Bug 41603

Created attachment 60509 [details] test case The interior of the ellipse is empty. In Opera 10.60 there is a black circle in the middle of the ellipse. According to my interpretation of section 13.3 from the SVG 1.1 (Second Edition) specification the pattern element defines a reference rectangle (the pattern tile) whose origin and dimensions are determined by the attributes x, y, width and height in the coordinate system specified by patternUnits. If there is no viewBox attribute, then the coordinates of the elements inside the pattern element are relative to the origin of the pattern tile: "The contents of the ‘pattern’ are relative to a new coordinate system. ... If there is no ‘viewBox’ attribute, then the new coordinate system has its origin at (x, y), where x is established by the ‘x’ attribute on the ‘pattern’ element, and y is established by the ‘y’ attribute on the ‘pattern’ element."
