Test program

When ClientSideGraphics registry key is set to "n", rendering is correct [1].
But when it is either set to "y" or doesn't exist (as default), rendering is
wrong [2]. It appears to look wrong because something goes wrong with
gdi32!Pie() function implementation - with ClientSideGraphics it calculates
positions differently from gdi32!Ellipse() with same rect passed.
You can see this using test program in attachment (compare top and bottom at
[3] - notice different pies at top-left and and the rightmost one).
