// Create a shader program with a vertex and fragments shader loading from
// source strings and vertex attributes assigned from a map before linking the
// shaders to the program, making it ready to use with glUseProgram(id)
// Inputs:
// geom_source string containing source code of geometry shader (can be
// "" to mean use default pass-through)
// vert_source string containing source code of vertex shader
// frag_source string containing source code of fragment shader
// attrib map containing table of vertex attribute strings add their
// correspondingly ids (generated previously using glBindAttribLocation)
// Outputs:
// id index id of created shader, set to 0 on error
// Returns true on success, false on error
//
// Note: Caller is responsible for making sure that current value of id is not
// leaking a shader (since it will be overwritten)
