Pietro Gagliardi 46e3fee40d Added a center point to scaling transforms. Fixed rotations on GTK+. 2015-10-12 01:43:12 -04:00
Pietro Gagliardi e51fd6e494 Implemented negative arcs on GTK+. 2015-10-11 21:18:39 -04:00
Pietro Gagliardi b09cdb5137 Made 90° point toward y=+∞. 2015-10-11 20:24:06 -04:00
Pietro Gagliardi 0ae3ef918d Implemented the matrix stuff on Windows. Also fixed the signature of uiDrawMatrixSkew(). 2015-10-11 12:36:48 -04:00
Pietro Gagliardi 87680a6470 Built the framework for matrices and transformations and implemented it on the GTK+ backend. Tests to come next. 2015-10-11 11:13:01 -04:00
Pietro Gagliardi 7fbabfd8ec Fixed the GTK+ drawing code to draw arc initial line segments in the correct place. 2015-10-10 08:44:12 -04:00
Pietro Gagliardi 3cbc3f3c67 Made arc angles counterclockwise on the GTK+ backend and fixed the sun in the Direct2D geometries howto. 2015-10-09 23:13:15 -04:00
Pietro Gagliardi 73d77ef38b Capped sweeps at 2π radians. 2015-10-09 22:00:41 -04:00
Pietro Gagliardi 2c7ed07747 Changed the arc functions to take a start angle and a sweep amount instead of a start angle and an end angle. This makes it easier to reason about sweeps > 2π radians. 2015-10-09 21:51:43 -04:00
Pietro Gagliardi 752467b543 Fixed up the GTK+ uiArea a bit. 2015-10-09 03:43:29 -04:00
Pietro Gagliardi ef04c18856 Merged the GTK+ uiArea implementation with its backend. Now we just have to move the test program. 2015-10-08 18:24:09 -04:00
