[0:25][Recap and plan for today]
[4:54][We want the ability to load multiple fonts]
[6:20][TODO(casey): Are there larger numbers than 4096...?][quote 180]
[7:06][Using more explicit asset structs in the asset packer]
[12:23][Moving the font loading code to a separate function]
[17:20][Freeing the memory taken by the fonts]
[18:25][We need at least a font for the game and another one for debug purposes]
[19:01][Our STB code path is broken for the moment]
[19:30][Making fonts available as usable assets]
[20:16][AddFontAsset]
[21:25][Pulling together duplicated code into AddAsset]
[27:39][Hardcoding the codepoint count until we know the range of characters we want to load]
[30:21][Initializing the global font device context at startup]
[36:34][Building the font tables]
[38:58][Writing the asset font information into the asset file]
[41:41][Faking the horizontal advance using the width of the current character]
[45:22][Loading the font data from the asset file]
[45:45][The codepoint loading gets tricky when using more than one asset file...]
[50:48][...but we can do the codepoint rebasing per file!]
[57:35][Q&A][:speech]
[58:05][@abnercoimbre][Give us a sec]
[58:25][@garlandobloom][I tried to explain to someone that a color is just a uint32 and I am not sure I got it across]
[59:01][Blackboard: "Color" -> Ambiguous term!]
[1:03:46][@Robrobby][You added Textmetrics into the struct and then decided to alloc it - why? And whats the benefit?]
[1:05:02][@ijustwantfood][About the language having different fonts. Would this apply to added packages by other people?]
[1:06:00][@garlandobloom][I'm talking about in terms of how the GPU cares about the color of a pixel, as opposed to a struct with float r,g,b,a. Which is not really necessary for a buffer thing]
[1:06:22][Blackboard: GPU \~ CPU]
[1:14:07][@An0nymal][Do any systems ever represent light as an actual frequency and change that value based on interaction with the simulated environment?]
[1:16:28][@cubercaleb][If you take in user input at some point will you worry about blocking Unicode control characters?]
[1:16:44][@Robrobby][So you care about the stack memory. When would you start to really measure it, or is some gut feeling enough? I would never had that idea before not getting an actual error]
[1:17:15][@TheSizik][What is HDR?]
[1:18:51][@EnemyMouse][Do you think there will be a time when CPU and main bandwidth is fast enough to replace GPUs entirely, going back to the days of software renderers?]
[1:19:12][Wind things down for dinner][:speech]
