GTK3 Image Scaling on Raspberry Pi Hiccups

If you read my previous post on GTK3 image scaling, you'll notice that GTK3 uses Cairo for the task. I compiled and tested the code on Raspberry Pi (B revision) but unfortunately the lag is noticeable, on the order of 1 second or more on 1366x768 LCD display. This is quite unacceptable for some "display-intensive" applications.

Anyway, this is without using any acceleration on the Pi's GPU because I have yet to make that works. I noticed a sort of GPU accelerated sample codes in the /opt directory on Raspbian but unfortunately, I have yet to be able to run the sample code successfully. Compiling the code runs just fine without problems but running the result always failed.
