If enabled in the preferences menu, pen and marker strokes will be
replaced by a simplified stroke after they are drawn.
The algorithm is very basic (for now): if three points are almost lined
up (the threshold angle can be specified in the config file), then the
middle one is removed. This is repeated over the whole stroke; new
polygons are then generated based on the simplified stroke points.
This typically cuts down on number of points and polygons by a factor of
about 10, while having minimal visual impact.
- Added a curveToPolygon function that creates a curved polygon,
eliminating the need to generate lots of small ones to make a curve look
smooth.
- Cleaned up the rest of the code a bit
- UBGraphicsScene calls UBGraphicsStroke::addPoint, which returns a list
of points that can be drawn. It may be none (e.g we discard very small
segments), one (if we do no interpolation) or several.
- Added a UBInterpolator base, abstract class. Various interpolation
methods can be added easily.
- Current methods: Basic spline (custom), Catmull-Rom spline (based on
alglib), and Bézier
- Added a setting to toggle interpolation. Added this to the UI as well
(widgets' size and position weren't necessarily calculated based on
their current screen, but on the entire desktop geometry)
This also fixes the skewing observed during podcast recording
- Moved all platform-specific code to UBPlatformUtils
- For now, removed support (on Linux) for checking whether onboard is
running when OpenBoard is started (it wasn't working anyway, but it needs a
cleaner solution for all 3 platforms)
