[sword-devel] SwordReader - Experimental Double Buffering added.

[David Trotz]

Hi all,
I have been thinking of ways to improve the amount of time it takes for 
the display to show anything when changing the text. In some cases its 
as much as 4 seconds! So I decided to take an approach used often in 
computer graphics, double buffering. In our case the buffer is an html 
page. I have implemented a system with two html displays, so that when 
there are 1500 characters ready to be processed I immediately show the 
text on the screen using the first html display, meanwhile I continue to 
load the rest of the text and once it is done I hide the first html page 
and show the other one which has the entire text in it. This approach is 
highly experimental and has kinks in it. I broke the verse scrolling but 
will fix it soon, I wanted to see how much faster this really is. It is 
definitely faster. Now that I know it will help I will begin the process 
of smoothing out my kinks. The code is in subversion.
