Bug 1560771 - Give proper line width range for core profile r=jgilbert

Browse Source 
Because glLineWidth is deprecated in newer versions of core opengl,
we currently ignore lineWidth when using core profile.  We should
probably also make ALIASED_LINE_WIDTH_RANGE match this behavior to
lessen confusion.
