2017-04-05VideoCommon: rework anamorphic widescreen heuristicMichael Maltese
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: Paper Mario: The Thousand-Year Door (Gecko widescreen code from Nintendont) C202F310 00000003 3DC08042 3DE03FD8 91EEF6D8 4E800020 60000000 00000000 04199598 4E800020 C200F500 00000004 3DE08082 3DC0402B 61CE12A2 91CFA1BC 60000000 387D015C 60000000 00000000 C200F508 00000004 3DE08082 3DC04063 61CEE8D3 91CFA1BC 60000000 7FC3F378 60000000 00000000 The Simpsons: Hit & Run (AR widescreen code from the wiki) 04004600 C002A604 04004604 C09F0014 04004608 FC002040 0400460C 4082000C 04004610 C002A608 04004614 EC630032 04004618 48220508 04041A5C 38600001 04224344 C002A60C 04224B1C 4BDDFAE4 044786B0 3FAAAAAB 04479F28 3FA33333

Fixes Projection alignment in some N64 VC games. The original code forgot to multiply rawProjection[1] and rawProjection[3].

These provide the same semantics, however aggregate initialization doesn't force the structs to be trivially copyable. memset, on the other hand, does.

2016-09-01VertexShaderManager: Explicitly use floating-point variant of abs.Jules Blok
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.
2016-09-01VertexShaderGen: Move the sonic epsilon hack to the vertex shader.Jules Blok
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.

It may be a bit weird to see calls to static functions in VertexManagerBase now, but at least it's easier to see what's going on.

2015-08-01Widescreen Heuristic: Cleanup code.Scott Mansell
2015-08-01Make the GameCube game widescreen heuristic smarter.Scott Mansell
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.
2015-07-27Heuristic to detect if a gamecube game is rendering 16:9 widescreen.Scott Mansell
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.

Had to re-do *ShaderManager so they saved their constant arrays instead of completly rebuilding them on restore state.

This shader constant was previously used for depth remapping in D3D and for pixel center correction. Now it only serves one purpose and the new name makes it clear.
