## References * See also #8617 ## PR Checklist * [x] Supports #3075 * [x] I work here. * [x] Manual test. ## Detailed Description of the Pull Request / Additional comments ### Window Title Generation Every time the renderer checks the title, it's doing two bad things that I've fixed: 1. It's assembling the prefix to the full title doing a concatenation. No one ever gets just the prefix ever after it is set besides the concat. So instead of storing prefix and the title, I store the assembled prefix + title and the bare title. 2. A copy must be made because it was returning `std::wstring` instead of `std::wstring&`. Now it returns the ref. ### Dirty Area Return Every time the renderer checks the dirty area, which is sometimes multiple times per pass (regular text printing, again for selection, etc.), a vector is created off the heap to return the rectangles. The consumers only ever iterate this data. Now we return a span over a rectangle or rectangles that the engine must store itself. 1. For some renderers, it's always a constant 1 element. They update that 1 element when dirty is queried and return it in the span with a span size of 1. 2. For other renderers with more complex behavior, they're already holding a cached vector of rectangles. Now it's effectively giving out the ref to those in the span for iteration. ### Bitmap Runs The `til::bitmap` used a `std::optional<std::vector<til::rectangle>>` inside itself to cache its runs and would clear the optional when the runs became invalidated. Unfortunately doing `.reset()` to clear the optional will destroy the underlying vector and have it release its memory. We know it's about to get reallocated again, so we're just going to make it a `std::pmr::vector` and give it a memory pool. The alternative solution here was to use a `bool` and `std::vector<til::rectangle>` and just flag when the vector was invalid, but that was honestly more code changes and I love excuses to try out PMR now. Also, instead of returning the ref to the vector... I'm just returning a span now. Everyone just iterates it anyway, may as well not share the implementation detail. ### UTF-8 conversions When testing with Terminal and looking at the `conhost.exe`'s PTY renderer, it spends a TON of allocation time on converting all the UTF-16 stuff inside to UTF-8 before it sends it out the PTY. This was because `ConvertToA` was allocating a string inside itself and returning it just to have it freed after printing and looping back around again... as a PTY does. The change here is to use `til::u16u8` that accepts a buffer out parameter so the caller can just hold onto it. ## Validation Steps Performed - [x] `big.txt` in conhost.exe (GDI renderer) - [x] `big.txt` in Terminal (DX, PTY renderer) - [x] Ensure WDDM and BGFX build under Razzle with this change.
