| 721 | * We should somehow handle translucent images. GTK can draw to X Drawables |
| 722 | * only, which don't support alpha. When we retrieve the image back from |
| 723 | * the server, translucency information is lost. There're several ways to |
| 724 | * work around this: |
| 725 | * 1) Subclass GdkPixmap and cache translucent objects on client side. This |
| 726 | * requires us to implement parts of X server drawing logic on client side. |
| 727 | * Many X requests can potentially be "translucent"; e.g. XDrawLine with |
| 728 | * fill=tile and a translucent tile is a "translucent" operation, whereas |
| 729 | * XDrawLine with fill=solid is an "opaque" one. Moreover themes can (and some |
| 730 | * do) intermix transparent and opaque operations which makes caching even |
| 731 | * more problematic. |
| 732 | * 2) Use Xorg 32bit ARGB visual when available. GDK has no native support |
| 733 | * for it (as of version 2.6). Also even in JDS 3 Xorg does not support |
| 734 | * these visuals by default, which makes optimizing for them pointless. |
| 735 | * We can consider doing this at a later point when ARGB visuals become more |
| 736 | * popular. |
| 737 | * 3') GTK has plans to use Cairo as its graphical backend (presumably in |
| 738 | * 2.8), and Cairo supports alpha. With it we could also get rid of the |
| 739 | * unnecessary round trip to server and do all the drawing on client side. |
| 740 | * 4) For now we draw to two different pixmaps and restore alpha channel by |
| 741 | * comparing results. This can be optimized by using subclassed pixmap and |
