Updates to make CX more compatible with Linux. The main thing was renaming CX::Instances::Display to CX::Instances::Disp to deal with the obnoxious Display struct in the X11 header. All examples brought up to date with new name.
Setup of OpenGL was improved to be more compatible with older hardware/Linux drivers.
A number of the changes in this commit are actually line ending disagreements between Windows and Linux, not legitimate changes.
