// Report is an unsual situation. This is somewhat similar
// to an assert but does not always represent a code bug.
// eg: Unable to load an icon.
//
#define Report(x) ASSERT(x) // Currently defined as an assert because I don't have time to rewrite another macro
/////////////////////////////////////////////////////////////////////
// Macro Endorse()
//
// This macro is mostly used when validating parameters.
// Some parameters are allowed to be NULL because they are optional
// or simply because the interface uses the NULL case as a valid
// input parameter. In this case the Endorse() macro is used to
// acknowledge the validity of such a parameter.
//
// REMARKS
// This macro is the opposite of Assert().
//
// EXAMPLE
// Endorse(p == NULL); // Code acknowledge p == NULL to not be (or not cause) an error
//
#define Endorse(x)
