+
+Coordinates:
+
+The image can be zoomed, can have a position offset, and additionally there is
+QScrollView's viewport. This means there are several coordinate systems.
+
+
+
+Let's start from simple things. Viewport ignored, zoom ignored:
+
+ A-----------------------------------
+ | |
+ | |
+ | B--------------------- |
+ | | | |
+ | | | |
+ | | | |
+ | | | |
+ | | | |
+ | | | |
+ | ---------------------C |
+ | |
+ | |
+ ------------------------------------
+
+
+The inner rectangle is the image, outer rectangle is the widget.
+A = [ 0, 0 ]
+B = [ mXOffset, mYOffset ]
+C = B + [ mDocument->width(), mDocument->height() ]
+
+
+
+The same, additionally the image is zoomed.
+
+A = [ 0, 0 ]
+B = [ mXOffset, mYOffset ]
+C = [ mZoom * mDocument->width(), mZoom * mDocument->height()) ]
+
+The groups of functions imageToWidget() and widgetToImage() do conversions
+between the image and widget coordinates, i.e. imageToWidget() accepts coordinates
+in the image (original,not zoomed,image's topleft corner is [0,0]) and returns
+coordinates in the picture above, widgetToImage() works the other way around.
+
+There's no bounds checking, so widgetToImage( A ) in the example above would
+return image coordinate with negative x,y.
+
+The widgetToImage() functions round the values (in order to have the conversion
+as approximate as possible). However when converting from widget to image and back
+this can result in the final rectangle being smaller than the original.
+The widgetToImageBounding() function converts from widget to image coordinates
+in a way which makes sure the reverse conversion will be at least as large
+as the original geometry.
+
+There are no conversion functions for only width/height, as their conversion
+depends on the position (because of the rounding etc.). For similar reasons
+conversions should not be done with the bottomright corner of a rectangle,
+but with the point next to it.
+
+
+
+For conversions from/to QScrollView's viewport, usually QScrollView methods should
+be used: contentsX(), contentsY(), contentsWidth(), contentsHeight(), visibleWidth(),
+visibleHeight(), contentsToViewport() and viewportToContents().
