| 939 // look-and-feel, if we sent whole images instead of just colors | |
| 940 // from the browser to the renderer. But even then, some themes | |
| 941 // would just break. | |
| 942 // | |
| 943 // So, instead, we don't even try to 100% replicate the look of | |
| 944 // the native scrollbar. We render our own version, but we make | |
| 945 // sure to pick colors that blend in nicely with the system GTK | |
| 946 // theme. In most cases, we can just sample a couple of pixels | |
| 947 // from the system scrollbar and use those colors to draw our | |
| 948 // scrollbar. | |
| 949 // | |
| 950 // This works fine for the track color and the overall thumb | |
| 951 // color. But it fails spectacularly for the outline color used | |
| 952 // around the thumb piece. Not all themes have a clearly defined | |
| 953 // outline. For some of them it is partially transparent, and for | |
| 954 // others the thickness is very unpredictable. | |
| 955 // | |
| 956 // So, instead of trying to approximate the system theme, we | |
| 957 // instead try to compute a reasonable looking choice based on the | |
| 958 // known color of the track and the thumb piece. This is difficult | |
| 959 // when trying to deal both with high- and low-contrast themes, | |
| 960 // and both with positive and inverted themes. | |
