Lioncash 9c1f9c1c00 ConstantManager: Use std::array where applicable
Modernizes the arrays and makes future simplifications possible (e.g. usages within the software renderer).

It also makes cases where we use array->pointer decay explicit.

Michael Maltese d10d09ccc1 VideoCommon: rework anamorphic widescreen heuristic
Some widescreen hacks (see below) properly force anamorphic output, but
don't make the last projection in a frame 16:9, so Dolphin doesn't
display it correctly.

This changes the heuristic code to assume a frame is anamorphic based on
the total number of vertex flushes in 4:3 and 16:9 projections that
frame. It also adds a bit of "aspect ratio inertia" by making it harder
to switch aspect ratios, which takes care of aspect ratio flickering
that some games / widescreen hacks would be susceptible with the new
logic.

I've tested this on SSX Tricky's native anamorphic support, Tom Clancy's
Splinter Cell (it stayed in 4:3 the whole time), and on the following
widescreen hacks for which the heuristic doesn't currently work:

Lioncash 8dcb05802b ShaderManagers: Use aggregate initialization for some variables.
These provide the same semantics, however aggregate initialization
doesn't force the structs to be trivially copyable. memset, on the other
hand, does.

Jules Blok 376cadb862 VertexShaderManager: Explicitly use floating-point variant of abs.
Some compilers don't have an automatic abs() overload for floats.
Doesn't really matter if they use the integer variant here, but
it's better to be explicit about the fact that we're using floats.

Jules Blok debaf63fe8 VertexShaderGen: Move the sonic epsilon hack to the vertex shader.
In the vertex shader we have control over the depth clipping planes,
so we don't have to offset every floating point value and lose accuracy.

VertexManagerBase now, but at least it's easier to see what's going on.

Scott Mansell a1df1f5ae4 Widescreen Heuristic: Cleanup code. 2015-08-01 14:39:34 +12:00
Scott Mansell 615e5db0cb Make the GameCube game widescreen heuristic smarter.
The last heuristic wasn't quite smart enough and had a few
false positives in Mario Kart: Double Dash and Metroid prime 2.

Now we only activate if the game is rendering a 16:9
projection to a 4:3 viewport.
2015-08-01 13:21:53 +12:00
Scott Mansell bb60bcc42d Heuristic to detect if a gamecube game is rendering 16:9 widescreen.
Someone suggested on IRC that we should make a database of memory
locations in GameCube games which contain the 'Widescreen' setting
so we can automatically detect if the game is in 4:3 or 16:9 mode.

But that's hardly optimal, when the game actually tells the gpu
what aspect ratio to render in. 10 min and 6 lines of code later,
this is the result. Not only does it detect the correct aspect ratio
it does so on the fly.

I'm a little suprised nobody thought about doing this before.

NanoByte011 937844b9e3 Initial port of zfreeze branch (3.5-1729)
Initial port of original zfreeze branch (3.5-1729) by neobrain into
most recent build of Dolphin.

Makes Rogue Squadron 2 very playable at full speed thanks to recent core
speedups made to Dolphin. Works on DirectX Video plugin only for now.

Enjoy!  and Merry Xmas!!
