sw_engine: fix comparison of integer expressions of different signedness

Some gcc versions and configurations was giving an error:
error: "comparison of integer expressions of different signedness: 'const SwCoord'
{aka 'const long int'} and 'uint32_t' {aka 'unsigned int'} [-Werror=sign-compare]"
This patch should fix the error
