This patch optimizes window resizes by assuming that if a widget has the same height at a width of 50 as with a width of 150, the height for width 100 will also be the same. The patch also further optimizes the cache allocator, now there are 2 pointer arrays of up to a maximum of 5 requests, the arrays will only be allocated if a request is ever made in that orientation and the array will be sparse until each request is made (i.e. if a label can only wrap to 3 lines, there will only be 3 out of a possible 5 SizeRequest structures allocated to cache it).
