-LIGHT FLARES
-
-A light flare is an effect that takes place inside the eye when bright light
-sources are visible. The size of the flare relative to the screen is nearly
-constant, irrespective of distance, but the intensity should be proportional to the
-projected area of the light source.
-
-A surface that has been flagged as having a light flare will calculate the depth
-buffer value that its midpoint should have when the surface is added.
-
-After all opaque surfaces have been rendered, the depth buffer is read back for
-each flare in view. If the point has not been obscured by a closer surface, the
-flare should be drawn.
-
-Surfaces that have a repeated texture should never be flagged as flaring, because
-there will only be a single flare added at the midpoint of the polygon.
-
-To prevent abrupt popping, the intensity of the flare is interpolated up and
-down as it changes visibility. This involves scene to scene state, unlike almost
-all other aspects of the renderer, and is complicated by the fact that a single
-frame may have multiple scenes.
-
-RB_RenderFlares() will be called once per view (twice in a mirrored scene, potentially
-up to five or more times in a frame with 3D status bar icons).

-// tr_font.c
-//
-//
-// The font system uses FreeType 2.x to render TrueType fonts for use within the game.
-// As of this writing ( Nov, 2000 ) Team Arena uses these fonts for all of the ui and
-// about 90% of the cgame presentation. A few areas of the CGAME were left uses the old
-// fonts since the code is shared with standard Q3A.
-//
-// If you include this font rendering code in a commercial product you MUST include the
-// following somewhere with your product, see www.freetype.org for specifics or changes.
-// The Freetype code also uses some hinting techniques that MIGHT infringe on patents
-// held by apple so be aware of that also.
-//
-// As of Q3A 1.25+ and Team Arena, we are shipping the game with the font rendering code
-// disabled. This removes any potential patent issues and it keeps us from having to
-// distribute an actual TrueTrype font which is 1. expensive to do and 2. seems to require
-// an act of god to accomplish.
-//
-// What we did was pre-render the fonts using FreeType ( which is why we leave the FreeType
-// credit in the credits ) and then saved off the glyph data and then hand touched up the
-// font bitmaps so they scale a bit better in GL.
-//
-// There are limitations in the way fonts are saved and reloaded in that it is based on
-// point size and not name. So if you pre-render Helvetica in 18 point and Impact in 18 point
-// you will end up with a single 18 point data file and image set. Typically you will want to
-// choose 3 sizes to best approximate the scaling you will be doing in the ui scripting system
-//
-// In the UI Scripting code, a scale of 1.0 is equal to a 48 point font. In Team Arena, we
-// use three or four scales, most of them exactly equaling the specific rendered size. We
-// rendered three sizes in Team Arena, 12, 16, and 20.
-//
-// To generate new font data you need to go through the following steps.
-// 1. delete the fontImage_x_xx.tga files and fontImage_xx.dat files from the fonts path.
-// 2. in a ui script, specificy a font, smallFont, and bigFont keyword with font name and
-// point size. the original TrueType fonts must exist in fonts at this point.
-// 3. run the game, you should see things normally.
-// 4. Exit the game and there will be three dat files and at least three tga files. The
-// tga's are in 256x256 pages so if it takes three images to render a 24 point font you
-// will end up with fontImage_0_24.tga through fontImage_2_24.tga
-// 5. In future runs of the game, the system looks for these images and data files when a s
-// specific point sized font is rendered and loads them for use.
-// 6. Because of the original beta nature of the FreeType code you will probably want to hand
-// touch the font bitmaps.
-//
-// Currently a define in the project turns on or off the FreeType code which is currently
-// defined out. To pre-render new fonts you need enable the define ( BUILD_FREETYPE ) and
-// uncheck the exclude from build check box in the FreeType2 area of the Renderer project.
