es: fix output of texture2DLodEXT in GLES shaders
remove unused file to avoid confusion (#12)
cleanup: remove glcpp.c to avoid confusion
fix 'invariant gl_Position;' declaration
tests: add sampler precision test
emit sampler precision when needed (+ tests)
tests: add test for default precision statements (wrong output now)
towards handling default precision statements, issue #10. Most code by John-Paul Ownby
default precision: do not insert variable declarations before it
