The current version of Form initFromArray: is broken in several ways.
I have modified the method in several ways to correct the problems that
I saw.
This version does a better job of tiling in forms with an aspectratios
between 0.5 and 1.5 i.e. 16 at 32 works ok, 16 at 64 does not.

initFromArray: array
"If the array is filled with SmallIntegers, make them
LargeIntegers. Fill the bitmap from array. If the array is shorter,
then cycle around in its contents until the bitmap is filled."
| currentIndex arraySize repeatCount |
(array anySatisfy: [ :each | each > 655535])
ifFalse: [^ self initFromArray: (array collect: [:each |
(each bitShift: 16) bitXor: each])].
currentIndex _ 0.
arraySize _ array size.
repeatCount _ (bits size / 32) ceiling sqrt.
1 to: bits size by: repeatCount do:
[:index | (currentIndex _ currentIndex + 1) > arraySize
ifTrue: [currentIndex _ 1].
index to: index + (repeatCount -1) do:[ :idx | bits at:
idx put: (array at: currentIndex)]].! !
