 * Several of the backend factory functions take config parameters. It should

-* Maybe change the shortcuts? One idea (add ctrl-alt in all cases):
-	1-3: select scale factor
-	2-4: normal, advmame, hq filters (all available as 2x and 3x)
-	5-9,0: the other scalers
-  Justification: We have so many scalers now, we are running out of keys
-  for them - and this way, we need a few less. Of course, the question remains
-  what happens if you press ctrl-alt-3 while 2xSai is scaler, what happens?
-  So maybe (again add ctrl-alt):
-    '+' / '-':
-         increase/decrease scale factor, cycling over the possible range.
-         So for a 2x-only scaler, it does nothing; for a scaler supporting
-         all scales from 1x to 4x, it works as usual (and pressing '+' in
-         4x mode goes to 1x)
-    1-9: switch between the "base" scalers: normal (point) scaler, advmame,
-         hq (high quality), 2xsai, super2xsai, supereagle, tv2x, dotmatrix, ...
 * Fix the "auto dirty rect" computing code - in particular, use a proper checksum
   algorithm, this should solve many of the problems with some luck
 * OpenGL code: either fix it (see open bug tracker items and various hacks in the code),

 ---- -----------------
 ScummVM offers several anti-aliasing filters to attempt to improve visual
 quality. These are the same filters used in many other emulators, such as
-MAME. 
-Note: the resolutions listed assume the game was originally 320x200
+MAME. These filters take the original game graphics, and scale it by a 
+certain fixed factor (usually 2x or 3x) before displaying them to you.
+So for example, if the game originally run at a resolution of 320x200
+(typical for most of the SCUMM games), then using a filter with scale
+factor 2x will effectively yield 640x400 graphics. Likewise with a 
+3x filter you'll get 960x600.
 
 They are:
-        normal     - No filtering, original 320x200 resolution. Fastest.
-        2x         - No filtering, double screen/window size to 640x400 
-                     (default)
-        3x         - No filtering, triple screen/window size to 960x600
-        2xsai      - 2xsai filtering, double screen/window size to 640x400
-        super2xsai - Enhanced 2xsai filtering. 640x400 screen/window size
-        supereagle - Less blurry than 2xsai, but slower. Also 640x400
-        advmame2x  - 640x400 scaling. Doesn't rely on blurring like 2xSAI.
-        advmame3x  - 960x600 scaling. Doesn't rely on blurring like 2xSAI.
-        hq2x       - 640x400 scaling. Doesn't rely on blurring like 2xSAI.
-        hq3x       - 960x600 scaling. Doesn't rely on blurring like 2xSAI.
-        tv2x       - 640x400 scaling. Horizontal scanlines.
-        dotmatrix  - 640x400 scaling. Dot matrix effect.
+        normal     - No filtering, no scaling. Fastest.
+        2x         - No filtering, factor 2x (default).
+        3x         - No filtering, factor 3x.
+        2xsai      - 2xsai filter, factor 2x.
+        super2xsai - Enhanced 2xsai filtering, factor 2x.
+        supereagle - Less blurry than 2xsai, but slower. Factor 2x.
+        advmame2x  - Doesn't rely on blurring like 2xSAI, fast. Factor 2x.
+        advmame3x  - Doesn't rely on blurring like 2xSAI, fast. Factor 3x.
+        hq2x       - Very nice high quality filter but slow. Factor 2x.
+        hq3x       - Very nice high quality filter but slow. Factor 3x.
+        tv2x       - Interlace filter, tries to emulate a TV. Factor 2x.
