Lazarus port of Tom Nuydens "Mr. Potato Head" GLSL demo using modern GL functionality

Thanks for the sample! One small nitpick: calls to LoadOpenGL('opengl32.dll'); Load_GL_version_1_2; ... Load_GL_version_3_2; - are not needed, at least not if you use units distributed with FPC. LoadOpenGL runs in GL unit initialization and the version loading functions cascade to lower versions.

Yeah, I actually remembered that a few days after I originally posted this.
