-----------
GraphicsContextCG::strokeRect modifies stroke thickness state
https://bugs.webkit.org/show_bug.cgi?id=321910
rdar://185084876
Reviewed by Mike Wyrzykowski.
Avoid calling the public GraphicsContext state setter function. This
will modify the context state, which is not the intention of the
strokeRect.
Instead, use the CGContext API directly.
Currently not possible to invoke the bug from web, but prevents future
state-related optimizations.
