-/**
- * Hack alert: gis-opengl.h needs to be included before gis-viewer
- * - GisViewer depends on GisObject for add/remove functions
- * - GisObject depends on GisOpenGL for load/unload functions
- * - GisOpenGL depends on GisViewer for inheritance
- *
- * The problem here is that GisOpenGL needs the GisViewer definition
- * but GisViewer only needs the typedefs (through GisObject),
- * so GisViewer needs to be included after the GisOpenGL typedefs but
- * before the GisOpenGL definition. This is handled internally by
- * gis-opengl.h
- *
- * This should probably be fixed, but making a GisGLObject interface
- * seems like too much work. Merging GisViewer and GisOpenGL would also work,
- * but I like the separate that that's provided by having two.
