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.
