add a bit more cairo drawing #1

Open galtgendo opened 12 years ago

galtgendo commented 12 years ago

Let's call this a second part of my patch. This one simplifies panel background drawing a bit and fixes a subtle bug (try setting alpha to 255 - it gets saved as 254 without this fix).

The patch is in the same place the first one - on sourcefoge.

Unfortunately, it seems it's as far as it can go in gtk2. For gtk3 some of the functions will need to be significantly rewritten. I'm not talking simply about expose-event -> draw, panel_determine_background works on GdkPixmaps for the sake of gdk_window_set_back_pixmap - in gtk3, the closest to it is gdk_window_set_background_pattern, which takes a cairo_pattern_t. This means, that the converting will have to be done differently, to prevent going between GdkPixbuf and cairo_surface_t more than once and loosing info.
