EvilSpirit	f8824e1fb2	Reimplement drawing of the mesh wireframe. OpenGL 2 and newer do not have the glPolygonMode(..., GL_LINES) API, so produce the wireframe on our side. It's somewhat slow, and draws every line three times, but it is cached when the OpenGL 2 renderer is used, and this should do for a debugging feature.	2016-11-18 02:40:43 +00:00
Evil-Spirit	1108a6f37d	Use Canvas::Stroke, not Canvas::Fill, for drawing a point. Our points are more like fat lines than actual quads, in that they are scale-invariant.	2016-10-11 23:32:05 +00:00
whitequark	4f49a8a9d4	Eliminate several memory leaks. All leaks found with valgrind while running the test suite. This commit also clears the Cairo cache to improve SNR of Valgrind output.	2016-08-01 05:39:18 +00:00
whitequark	8960ee365a	Add a new renderer that prepares geometry for 2d backends. SurfaceRenderer is a new renderer implementing the Canvas interface running entirely on the CPU; it projects strokes and triangles in the exact same way as OpenGL would, and it can be used for rendering into raster or vector 2d surfaces.	2016-08-01 00:48:37 +00:00
