bug #230 Revert to Xinerama 1.1 In order to make a "quick" release it has
been decided that the priority is to preserve the server's internal API/ABI so that third-party drivers that depend on symbols like noPanoramiXExtension, etc., would not need to be recompiled. Toobad gcc on Linux doesn't support ELF's weak symbols as that would have been a reasonable solution for preserving the ABI. N.B.: While symbols, i.e. functions and variables revert to the old name, I did not revert build names, i.e. -DXINERAMA, to the old -DPANORAMIX. There was no need, and it's just a build issue that has no impact on the binary output of the build.
