ATL
- Image blocks become timelines: picture steps with dissolve, parallel, contains,
finite repeat, time, function f(trans, st, at), calls of other transforms with
arguments, on hover/idle events for buttons. Animations stop when their element
leaves the page
- Pictures defined by an expression (get_face_path("base")) are drawn at show time
- Purely graphical hints (shader, mesh, gl_*, u_*) are accepted and dropped
Colour
- matrixcolor and im.matrix.* as 5x5 matrices combined with `*`, applied through SVG
filters; im.MatrixColor/Scale/Crop/Blur/Composite and Text/Image as values
Python
- match statement, re/copy/time/datetime/defaultdict/functools.partial, more
str/dict methods, Character(...) created by code
- narrator("..."), Character calls, renpy.say and renpy.show/hide with expressions in
Python blocks become script nodes
- Audit follows reachability: functions and classes nothing refers to (custom
statement lexers, unused tools) no longer block an import
Docs: README and ARCHITECTURE now describe a multi-engine library (GameMaker and
QSP planned). Tests for the new runtime pieces.
