Effect › Distort › Glass… offered only its four built-in textures. The
reference app's Texture menu also has Load Texture, which takes an
image file as the glass surface.
The Glass dialog now has a Load Texture… button. It reads a PNG, JPEG,
GIF, WebP, TIFF, BMP, PSD or PSB file within the pixel allowance the
renderer draws images in, and the Texture menu gains Loaded Texture.
The effect stores the image's gray levels in `textureImage` as a
grayscale PNG in base64, so the document saves the texture with the
effect, and copies of the effect carry it. effect.apply and
effect.setParams take `textureImage` as {path}, {name, dataBase64} or
the stored string; any other value is an error.
The texture lies one image pixel per point at Scaling 100%, centered on
the object and repeated. Each pixel's luma is the surface's height,
from 0 for black to 1 pt for white, and a transparent pixel counts as
middle gray. A Glass without `textureImage` draws and saves as before.

Free Distort's dialog showed the four corners as read-only text, and
so did the Appearance panel's inline editor. Only effect.apply and
effect.setParams could set them.
The dialog now shows a box in the proportions of the first selected
object's bounds with a handle on each corner. Dragging a handle moves
that corner, and the preview follows. A handle focused by a click or
Tab moves 1% of the box with each arrow key, and 10% with Shift. Reset
puts the four corners back on the box. Each handle has a
screen-reader name. On the corners row of the Appearance panel's
inline editor, Edit… opens the dialog.

Engine: effect.move {from, to, fromItem?, toItem?, copy?}; appearance.showAllHidden;
appearance.duplicateItem takes to? and indices?; appearance.removeItem takes indices?;
Appearance::has_hidden/show_all. UI: effect.dialog takes index? (edit in place via
effect.setParams) and opens the effectExists question for an effect already in the list.
