Good catch! A couple of fixed still needed, though.

This should be (ctx->params is not set yet either):
if (ctx == NULL) {
// Call renderer delete explicitly. Context is not initialized yet, so we cannot call nvgDeleteInternal() which usually calls the function.
if (params->renderDelete != NULL)
params->renderDelete(params->userPtr);
return NULL;
}

ctx can't be != NULL on error path, nvgDeleteInternal can return immediately (if (ctx == NULL) return;) without userPtr cleanup => "gl" can leak.
