Revert the recent zcomploc changes including the Graphic_Fixes merge.

Reason:
- It's wrong, zcomploc can't be emulated perfectly in HW backends without severely impacting performance.
- It provides virtually no advantages over the previous hack while introducing lots of code.
- There is a better alternative: If people insist on having some sort of valid zcomploc emulation, I suggest rendering each primitive separately while using a _clean_ dual-pass approach to emulate zcomploc.

This reverts commit 0efd4e5c29766ba5f5d22204339637ade9ccec83.
This reverts commit b4ec836aca4392a86b864dc58b1030ca616fe0d5.
This reverts commit bb4c9e2205d4117f48fd4ca50774ee56c28c92e4.
This reverts commit 146b02615c07dd52dddaa18b7e23d09bc23b549e.
