graphene:with-sizes (vars &body body)

s1 ... sn -- newly created graphene:size-t instances
body -- a body that uses the bindings s1 ... sn

The graphene:with-sizes macro creates new variable bindings and executes the body that use these bindings. The macro performs the bindings sequentially, like the let* macro.

Each size can be initialized with values using the syntax for the graphene:with-size macro. See also the graphene:with-size documentation.

        (list (graphene:size-width s3) (graphene:size-height s3))))
=> ((0.0 0.0) (1.2 1.3) (1.2 1.3))
