desktop-main.cpp: round the fractional part of the GL version
When verMinor is extracted with the glGetString() method,
use roundf() to round the GL MINOR version to an integer.
2.1 is split in 2 and 1.
Without this patch rounding issues are present as for 32bit IEEE
the default rounding makes (0.1f * 10.f) into 0.999999f.
Given the MINOR is a single digit for GL, calling roundf() on
0.999999 gives the expected result 1 for the MINOR.
