OpenGL C$++-$ Write a display$()$ function that draws the IBM logo$.$ You should

assume that the view volume goes from $0$ to $15$ in the y axis and that the thickness of each

bar in the logo is $1.$

You may want to use the following functions:

$1.$ drawCircle$($cx$,$ cy$,$ r$)$ which draws a filled circle centered at location

$($cx$,$ cy$)$ with radius r$.$

$2.$ drawArc$($float cx$,$ float cy$,$ float r$,$ float startAngle, float

endAngle$)$ which draws an arc of a circle of radius r$,$ centered at $($cx$,$ cy$)$ from

startAngle to endAngle.

$3.$ OpenGl function glRecti$($x$1,$y$1,$x$2,$y$2)$ which draws a filled rectangle between integer

corners $($x$1,$y$1)$ and $($x$2,$ y$2).$

HINT: Consider drawing some polygons and then $$erasing$$ some portions of them.
