// *** Code sequence for headers ***
// IMPORTANT: These items are in a carefully constructed order. DO NOT REARRANGE
// without checking with experienced devs! Various subtle things WILL break.
//
// We realize this is a bit (!) of a mess and hope to make further cleanups in a future release.
//
// A: Define themable header parsing
// B: Send HTTP headers that come before any html
// C: Send start of HTML
// D: Send CSS
// E: Send JS
// F: Send Meta Tags and Icon links
// G: Send final theme headers (theme_head() function)
// H: Generate JS for image preloading (setup for onload)
// I: Calculate onload() JS functions to be called
// J: Send end of html <head> and start of <body>
// K: (The rest is ignored for popups, which have no menus)
// L: (optional) Body JS to disable right clicks
// M: Send top of body for custom pages and for news
// N: Send other top-of-body HTML
//
// Load order notes for devs
// * Browsers wait until ALL HTML has loaded before executing ANY JS
// * The last CSS tag downloaded supercedes earlier CSS tags
// * Browsers don't care when Meta tags are loaded. We load last due to
// a quirk of e107's log subsystem.
// * Multiple external <link> file references slow down page load. Each one requires
// browser-server interaction even when cached.
