Subject: [PATCH] sproingies/RenderSproingie: limit shift value

gcc49 sanitizer detected the following error:
../../../hacks/glx/sproingies.c:554:24: runtime error: shift exponent 32 is too large for 32-bit type 'int'

This means that thisSproingie->frame - BOOM_FRAME can be no less than
32. So just clipping this value to 31 to make it sure that shift exponent
is in the range for int.
