In fact "for xy DrawRectangle" is used only to convert the wxWidgets internal image format to the Cairo internal image format. The cost is low, because it is executed only once for a new bitmap. >>From what I remember from OPENGL_GAL the proper way to develop it would be by >>adding a new "draw element" using a new shader for draw a texture and by >>uploading the images data to GPU textures. > > I believe the GAL specialists will have a good understanding how to add that > feature.
