Detailed Description

Represents the typecasting of an array. Arrays cannot be directly casted in SkSL (or GLSL), but type narrowing can cause an array to be implicitly casted. For instance, the expression myHalf2Array == float[2](a, b) should be allowed when narrowing conversions are enabled; this constructor allows the necessary array-type conversion to be represented in IR.

These always contain exactly 1 array of matching size, and are never constant.
