- Add simd aligned_vec3 (and sse aligned_dvec3 - 2 x xmm) - Fast packed_vec3 <=> aligned_vec3 and packed_vec4 <=> aligned_vec4 conversion - Fast aligned_vec3 <=> aligned_vec4 conversion - Optimized aligned_mat x aligned_mat and aligned_mat x aligned_vec - Inverse aligned_mat3 simd version (actually slower than ssid on my computer even it has 30% less instruction ?)
