In order to build libEGL without explicitly setting a dependency
on the Renderer and Reactor projects, the Renderer's Surface class
must be linked with libEGL. That was causing an issue where the 2
Surface.so objects were colliding on Linux. In order to solve the
issue, libEGL/Surface.* was renamed to libEGL/EGLSurface.*
