Add tests for ShmGetImage
Similar to GetImage and ShmPutImage, test the performance of retrieving
pixel data from the X server without the overhead of copying the pixels.
In the upper bound, using XShmGetImage, the performance will be limited
by the RTT latency (x11perf -prop). However, comparing the scaling factors
of XShmGetImage and XGetImage will give some insight into the driver
efficiency.
