raiden2cop: fixed negative float to unsigned int implicit conversion

Browse Source 
This caused issues on ARM hosts where result of such
conversion is always 0. Casting the negative float to
signed int resolves the issue. Without this fix some sprites
had wrong rotation and also bullet direction was not
always correct on ARM host. The fix was tested on Intel
and ARM host, both platform work OK.
