Fixed bug #831 Andrey 2009-10-09 08:08:04 PDT gapi_hires_fix I made a mistake with the conclusions. And last time I as was mistaken with conclusions. Now I thought about in more detail the algorithm works. I have made it that the project fheroes2 well worked. The result of my work in attachment. I have a possibility to check up it on different models pocketpc. I checked various modes screen of 320x320, 320x240, 640x480, 800x400.
