// The main change between this function and the Apple version is that
// this one counts the number of errors, and silently ignores errors
// after the first three.
// This is because some users discovered that RedPill would report GL
// errors *even when everything worked fine*, and their system log would
// get filled up with 30 lines of error text every second until it ate
// all available disk space. Ouch!
