enum ContinueBlockType
Name Value Comments
ContinueNone 0 --
ForLoop 1

Continue block is branchless and has at least one instruction.
WhileLoop 2

Noop continue block.
DoWhileLoop 3

Continue block is conditional.
ComplexLoop 4

Highly unlikely that anything will use this,
since it is really awkward/impossible to express in GLSL.
