Draw image on uiArea?

[joao678]

Is there any good and performace effective way of rendering png images inside a uiArea?
Looked at the code and dosen't seem to have a dedicated method of drawing an image

Perhaps something could be added quickly if someone has, say, libpng or something
installed? Just as a temporary workaround. In gtk gdk-pixbuf is used I think.

Performance-optimized support of bitmap drawing was proposed in #386

I added a code example and an image custom control implementation that automates it in my Glimmer DSL for LibUI Ruby library over here:
