A simple 2D graphics library for turning simple 2D shapes and text into textured triangles.

Made for egui.

Create some Shape:s and pass them to tessellate_shapes to generate Mesh:es that you can then paint using some graphics API of your choice (e.g. OpenGL).

Coordinate system

The left-top corner of the screen is (0.0, 0.0), with X increasing to the right and Y increasing downwards.

epaint uses logical points as its coordinate system. Those related to physical pixels by the pixels_per_point scale factor. For example, a high-dpi screeen can have pixels_per_point = 2.0, meaning there are two physical screen pixels for each logical point.

Angles are in radians, and are measured clockwise from the X-axis, which has angle=0.
