But actually, it was totally unnecessary! MorphicTransform's scaling method
arguments were either named (unhelpfully) 's' or (misleadingly) 'aFloat',
but apparently, I can just pass aPoint to scale x and y separately :)

Good to know!

BTW I found a bug in isPureTranslation:
(MorphicTransform offset:10@10 angle:0 degreesToRadians�� scale:1) isPureTranslation -> true
(MorphicTransform offset:10@10 angle:0 degreesToRadians�� scale:1@1) isPureTranslation -> false

��

So I'm back to the simple version...
drawOn: aCanvas

�� | transform widthScale heightScale |
�� widthScale := self innerBounds width / self image width.
�� heightScale := self innerBounds height / self image height.
�� transform := MorphicTransform new withScale: widthScale@heightScale.
�� aCanvas warpImage: self image transform: transform at: self innerBounds
origin

Thanks for talking me through it! I learned a lot...

Cheers,
Sean
