Pragtical v3.4.3 Release
This release fixes various issues reported on GitHub, and introduces some new features and enhacements. The big ticket for this release is overall better scaling behaviour. macOS builds now default to the plain software renderer which is faster. This is possible because various releases ago (almost a year?) we introduced functionality to detect the display scale at runtime, meaning that scaling should be properly performed Lua side instead of relying on the renderer. The SDL Renderer (aka "hardware renderer") is still available but since the glyph loading optimizations, it needs some adjustments to better handle the positions and sizes of fonts when the scale is >= 2.
