* Implement vertical subpixel positioning where availableEskil Abrahamsen Blomfeldt2021-01-251-6/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For some use cases, vertical subpixel positioning may be useful, as it allows you to vertically align text with other painting primitives. This does impose an overhead, so we make it opt-int with a render hint on the painter. Note that this is only supported on Freetype currently. It might be possible to support on older macOS versions, prior to Mojave (which has disabled subpixel positioning entirely), but since it would have limited usefulness and Freetype is cross-platform anyway, I skipped that. Note: This drive-by-fixes an issue with subpixel positioning where glyphs would always be offset by 1/64, because we added the aliasing offset *after* we had determined the closest subpixel position. The idea of this, as far as I can understand, is rather to snap to nearest subpixel position upwards, not to add an offset to all glyphs, so it should be added before finding the correct position. It had a subtle visual effect when animating the position. It might be that we could get rid of it entirely, as I haven't been able to reproduce any issues with that, but I have moved it instead, to match what I believe the intention was. [ChangeLog][QtGui][Text] Added render hint flag QPainter::VerticalSubpixelPositioning which will position text at subpixel positions vertically whenever supported. In absence of this, text position will be rounded vertically as before.
