This is a backport of 1.15's terminal rendering code with some further improvements. This duplicates a fair bit of code, and is much more efficient. I expect the work done in #409 will supersede this, but that's unlikely to make its way into the next release so it's worth getting this in for now. - Refactor a lot of common terminal code into `FixedWithFontRenderer`. This shouldn't change any behaviour, but makes a lot of our terminal renderers (printed pages, terminals, monitors) a lot cleaner. - Terminal rendering is done using a single mode/vertex format. Rather than drawing an untextured quad for the background colours, we use an entirely white piece of the terminal font. This allows us to batch draws together more elegantly. - Some minor optimisations: - Skip rendering `"\0"` and `" "` characters. These characters occur pretty often, especially on blank monitors and, as the font is empty here, it is safe to skip them. - Batch together adjacent background cells of the same colour. Again, most terminals will have large runs of the same colour, so this is a worthwhile optimisation. These optimisations do mean that terminal performance is no longer consistent as "noisy" terminals will have worse performance. This is annoying, but still worthwhile. - Switch monitor rendering over to use VBOs. We also add a config option to switch between rendering backends. By default we'll choose the best one compatible with your GPU, but there is a config option to switch between VBOS (reasonable performance) and display lists (bad). When benchmarking 30 full-sized monitors rendering a static image, this improves my FPS[^1] from 7 to 95. This is obviously an extreme case - monitor updates are still slow, and so more frequently updating screens will still be less than stellar. [^1]: My graphics card is an Intel HD Graphics 520. Obviously numbers will vary. |
