SnapVector issues with old QVMs

[Thilo Schulz]

Hello,

I have a few qvms for older q3 versions which use a SnapVector() with int 
casts to round the vector. In older versions, this was rounded non-ansi like 
to the nearest int. I have seen syscall traps to implement SnapVector in the 
engine itself that emulate this behaviour. Sadly, this is not being used in 
the old qvms. Since I have little knowledge of assembler and no knowledge 
about how the vm interpreter / JIT-compiler etc. work, I wanted to know 
whether there is a _feasible_ way to revert the rounding behaviour with ints 
to the previous state.
I want to avoid having to compile new QVMs since this would lead to 
incompatibilities with already-existing clients using the old qvms.
Judging from the many platforms already supported, recompiling the qvms and 
redistributing them would be the only alternative... am I correct with this 
assumption?
