#define_method makes somewhat slower methods than alias_method.
If an app is making lots of GL calls, it might cause some slowdown.

I doubt it makes much change in real applications, but here's a silly
micro-benchmark anyhow:

$ ruby bench_alias_define.rb
      user     system      total        real
Foo  0.200000   0.030000   0.230000 (  0.224021)
FooAlias  0.190000   0.030000   0.220000 (  0.222571)
FooDelegate  0.810000   0.100000   0.910000 (  0.909526)
