+# This exerises a bug found in a Doom shader were the lessThan() comparision

here are some more typos to fix:
were -> where
exerises -> exercises
comparision -> comparison
againsts -> against
For me running this throws following assert:
shader_runner: ../src/compiler/glsl/ir.cpp:491:
ir_expression::ir_expression(int, ir_rvalue*, ir_rvalue*): Assertion
`op0->type == op1->type' failed.
Is this the issue?
