[Nooby Question] Scale Pixmap / Image

[Rashid]

Hi guys,

is there a way to scale a pixmap / image / frame buffer content with
native xlib-Code. Im developing for a mobile phone with a very limited
bus from the cpu to the gpu (yes its !#°"§*$&/() freerunner). 

I can let my apps run at normal speed at 320x240. But 640x480 should be
possible. A simple scale factor 2 would be enough. Like

PixMap BigPixMap = ScalePixmap(small); //or something

I googled for it but didnt found anything about it.
