Cache image data in gtk graphics driver

Description

Hello,

I noticed that the gtk_drawing_area graphics driver keeps opening image files at runtime. With a simple caching algorithm constant filesystem operations and image decompression can be avoided which improves performance. On map areas with a lot of POI icons this can save large amount of cpu time. The attached patch stores cached uncompressed image data in a hash map avoiding unnecessary repeated image loading.
