Each of the fifteen Warp styles now bends the bounds as one Bézier patch. The style sets the patch's control points from the bend and the size of the bounds, the horizontal distortion scales each column of control points about its middle, and the vertical distortion scales each row. The Warp effects and warp envelopes share the map (`WarpNet`). Content with no width or no height takes the middle of the patch along that side. A warp carries the map it draws with as `version`. New warps, the built-in graphic styles' Warps and warps opened from .ai files get 1. Warps in .vectorcraft documents saved before the version existed read as 0 and keep the earlier map, so those documents keep their look. Edits keep a warp's version, and Warp Options editing several objects keeps each one's own. effect.apply, effect.setParams and the warp envelope commands take `version` 0 or 1 (`1.0` counts as 1) and refuse any other value. An .ai file holds a warp's settings and not its version, so a version 0 warp saved to .ai opens again with version 1. The .ai writer compares a style's settings without the version, so saved warps still export as editable effects.
