Arbitrary, non-destructive canvas rotation does not exist in Photoshop. Painter, Manga Studio, OpenCanvas, Comicwerks and many other applications do, however, support it.

In Painter, Alt (or Option on Mac) + Space rotates the canvas on the fly. Painter’s brush algorithms are far better than Photoshop’s. The dampening and cubic interpolation (plus the ability to recognize stroke velocity as a determinate for how the brush reacts) is way above the latter’s brush engine.
