It could surely be a lot smaller if it were restricted to a single multiplatform toolkit such as wxWindows. However, users seem to prefer platform-specific code, leading to a lot of duplication. It's not clear to me that's bad, given that both user preference and developer skills are often very platform-specific. By comparison, it's hard to say exactly (depends on what you mean by "display"), but XEmacs's display engine is about 3.5KLOC of C code, of which less than 1.5KLOC are in the platform-independent parts.
