Transform: support tiled rendering
ReConverge: Use OFX 1.2 DoubleType
Transform: many changes, see below
- implement separate X/Y skew
- the canonical coordinates of the center of the first pixel are (0.5,0.5)
- fix regionsOfInterest for bilinear and bicubic filter (fixes the black lines bug)
- antialias borders when blackoutside is checked
- the transform is now exactly the same as in Nuke
- don’t use normalized parameters, they are deprecated
