Fixed bug 3134 - CalculateXRandRRefreshRate() returns incorrect refresh rate due to floating point truncation.

Michael

In SDL_x11modes.c the CalculateXRandRRefreshRate() function performs integer math on values that may return fractional results. This causes a value that would be calculated as 59.99972... to be returned as 59. In Linux the xrandr command returns 60Hz for this particular display mode yet SDL returns 59Hz.

I suggest this function be updated to correctly round the result of the calculation instead of truncating the result.
