Jasper St. Pierre	69347fff09	scroll-view-fade: Only calculate the ratios if they're needed ... This prevents some calculations being done for poor drivers with bad optimizers. https://bugzilla.gnome.org/show_bug.cgi?id=689249	2012-11-29 16:17:09 -05:00
Jasper St. Pierre	5c439f4e9c	scroll-view-fade: Do the offset math in the shader ... This doesn't (or shouldn't) change the visual appearance of the fade effect, but does do all the testing math inside the shader, rather than on the CPU. This will make fading the offset much easier in the future. https://bugzilla.gnome.org/show_bug.cgi?id=689249	2012-11-29 16:17:09 -05:00
Jasper St. Pierre	c84236ed73	scroll-view-fade: Use GLSL 1.20 ... GLSL 1.20 is a better language, and we'll rely on it in future updates. This doesn't have any additional constraints, since GLSL 1.20 was standardized before GLSL-supporting drivers came out. https://bugzilla.gnome.org/show_bug.cgi?id=689249	2012-11-29 16:17:09 -05:00
Jasper St. Pierre	ae1a3a0cb2	scroll-view-fade: Clean up GLSL ... Basic cleanup of what we're doing already. This moves a bunch of the "inside the fade area" checks to the top, before doing any calculations. https://bugzilla.gnome.org/show_bug.cgi?id=689249	2012-11-29 16:17:09 -05:00
Jasper St. Pierre	b3fea016f1	scroll-view-fade: Put the shader in another file ... This doesn't make any changes to the shader outside of adding a header; it simply makes changes in the future easier to edit. https://bugzilla.gnome.org/show_bug.cgi?id=689249	2012-11-29 16:17:09 -05:00
