// Render flags
 
// ------------
 
//
 
// Render flags for a model are provided, believe it or not, in
 
// the model<nowiki>’</nowiki>s filename. If the leading character is an underline
 
// then the following is a hash for a binary attribute map where
 
//
 
//  00000 ( 0) = no flags
 
//  00001 ( 1) = translucency (colour blending?)
 
//  00010 ( 2) = animate texture UV coordinates
 
//  00100 ( 4) = transparency (alpha blending?)
 
//  10000 (16) = colour key transparency
 
//
 
// The hash depends on character
 
//
 
//  <nowiki>’</nowiki>0<nowiki>’</nowiki>..<nowiki>’</nowiki>9<nowiki>’</nowiki>: flag <nowiki>|</nowiki>= char - 48 (==<nowiki>></nowiki> 0 .. 9)
 
//  <nowiki>’</nowiki>A<nowiki>’</nowiki>..<nowiki>’</nowiki>Z<nowiki>’</nowiki>: flag <nowiki>|</nowiki>= char - 55 (==<nowiki>></nowiki> 10 .. 35)
 
//  <nowiki>’</nowiki>a<nowiki>’</nowiki>..<nowiki>’</nowiki>z<nowiki>’</nowiki>: flag <nowiki>|</nowiki>= char - 87 (==<nowiki>></nowiki> 10 .. 35)
 
//
 
// The most common filename prefixes (actually, the only ones
 
// present in Dark Omen) are:
 
//
 
//   "_4": 00000100 (transparency)
 
//   "_6": 00000110 (transparecy and animated texture coordinates)
 
//   "_7": 00000111 (translucency, animated texture coordinates, and transparency)
 
//   "_K": 00010100 (transparency and colour keying)
