039e6dc8db Relaxed the assertion for the 3x scaler a bit. Since it uses pointers to 
uint16, it should be enough that dstPtr is even; it doesn't have to be a
multiple of four.

The old assertion failed for me when I used the 3x scaler without aspect
ratio correction.

2a9c6f6d5f Base our advmame scalers on the official Scale2x source - this way we can easily update to new version and benefit from their optimizations (e.g. MMX support)

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)

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 :-)

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.
