1/* filter.c version 0.7
2* contient les filtres applicable a un buffer
3* creation : 01/10/2000
4* -ajout de sinFilter()
5* -ajout de zoomFilter()
6* -copie de zoomFilter() en zoomFilterRGB(), gérant les 3 couleurs
7* -optimisation de sinFilter (utilisant une table de sin)
8* -asm
9* -optimisation de la procedure de génération du buffer de transformation
10* la vitesse est maintenant comprise dans [0..128] au lieu de [0..100]
