// Note ----------------------------------------------------------------------
|
||||||
|
// Safari is the only browser that currently supports 3D transforms.
|
||||||
|
// Because of that it can be important to control whether a given 2D transform
|
||||||
|
// uses the full range of experimental browser prefixes, or only the 3D list.
|
||||||
|
// To make that easy, all 2D transforms include an browser-targeting toggle ($only3d)
|
||||||
|
// to switch between the two support lists. The toggle defaults to 'false' (2D),
|
||||||
|
// and also accepts 'true' (3D). Currently the lists are as follows:
|
||||||
|
// 2D: Mozilla, Webkit, Opera, Official
|
||||||
|
// 3D: Webkit, Official **(Only Safari Supports 3D perspective)**
|
||||||
|
|
||||||
|
// Available Transforms ------------------------------------------------------
|
||||||
|
// - Scale (2d and 3d)
|
||||||
|
// - Rotate (2d and 3d)
|
||||||
|
// - Translate (2d and 3d)
|
||||||
|
// - Skew (2d only)
|
||||||
|
|
||||||
|
// Transform Parameters ------------------------------------------------------
