a02c13a52e fix scaler compilation for MSVC6. However, the produced code stll seems to be incorrect... Jamieson, maybe the MSVC6_COMPAT should be re-added then after all?

7ccafa467c synced hq2x with upstream changes; some performance tweaks to hq2x/hq3x (I think for bigger speed improvement we'd have to use ASM (with C++ fallback of course)...

c40e7d68a5 templatized more of the scalers; also introduced template struct ColorMasks (shortens/simplifies other code a bit)

4a7385b4e7 split out scalers into separate source files in common/scaler; some optimizations (in particular, the hq2x/hq3x scalers now are compiled into two versions, one for 555 and one for 565 mode)

1d40ce68c2 get rid of explicit redMask/blueMask and use redBlueMask instead (this will be useful should we choose to templatize the scalers for 555/565 mode optimizations)

44c0654ffd Fixed template function compile quirks under MSVC6. 
Apparently MSVC6 does not like overloading of template
functions when the template arguments vary between
versions of the overloaded function. I replaced
interpolate16 with functions that have two different
names, so MSVC6 won't see them as being the same
function with [it insists] the same number of template
arguments.

e032e79a4a added hq2x scaler (no, I am not going to add hq4x anytime soon. It would be another 4-5000 lines of code, and scaler.cpp already takes far too long to compile. Maybe we should seperate the scalers into several files in common/scaler/ ?)

d87f65ff06 added a FIXME (regarding optimization) to INTERPOLATE; added new template function interpolate16 which is used by hq3x (advantage of the old trick which abused Q_INTERPOLATE: smaller & better optimized code; very easy to adapt the function for other uses, like for hq2x/hq3x. Drawback: scaler.cpp takes even longer to compile now :-)

0df319e952 #include cleanup (explicityl specify the location for headers from common/, so that we at some point can get rid of -Icommon; exception is made for stdafx.h, since a) we might want to rename it and b) might want to move it to the top level)

31bdf9f450 undoing this optimization: despite my initial sureness about this being correct - I was wrong :-) just plug in 0xFFFFFFFF to see it (roughly spoken, we can loose the uppermost bits if we shift after the addition instead of before it)

160c4f9104 Fixed the last (?) glitches around the mouse cursor [*] in aspect-ratio 
correction mode by making sure that dirty rects always start on a line
that won't have its colours changed by the stretching function. This was
probably only noticeable when using the 1x scaler.

[*] Actually, the glitches weren't specific to the mouse cursor, but it was
    useful for triggering them.

d7ef626b42 fix advmame scaler ('flickering', observable in e.g. Sam&Max, and the left-screen-border-black bug). Note: this change might look fishy to you but is perfectly legal because our frame buffers put a border around the screen data to accomodate for this
