Don't assume QSurfaceFormat's stencil buffer size is >= 0
The value -1 is used to indicate no stencil buffer, so we have to check for sizes <= 0 when deciding whether or not to triangulate the path in QOpenGL2PaintEngineExPrivate::fill(). This fixes an issue where filling a path would end up filling the whole outline of the path, which was very visible with fonts over a certain size (when we go from using the glyph cache to drawing filled paths for each glyph).
