-- Load a resizable 1-d frame. p contains an odd number of parts.
-- Even parts are resized; odd parts are not (unless the requested
-- width is too small). The frame is centered on the midway part
-- of p; parts to the left and right are anchored on the inside.
--
-- A 3-part frame; the center third is dynamic, expanding outwards
-- in both directions:
-- p = { 1/3, 1/3, 1/3 };
-- --oo--
-- --oooooooooo--
--
-- A 2-part frame. The left half is static, the right side dynamic;
-- the left part stays in place as the right half expands to the right,
-- with the frame centered on the boundary:
-- <<--
-- <<-----------
-- p = { 1/2, 0, 0, 1/2, 0 };
--
-- A 5-part frame, with an anchored center and static caps on each
-- end, expanding outwards:
-- <<--oo-->>
-- <<----------oo---------->>
-- p = { 1/5, 1/5, 1/10, 0, 1/10, 1/5, 1/5 };
