c7e6f051e4 Split the texture application into two stages. 
The latter simply applies the texture.

This makes our IsAlphaTestTriviallyTrue() check correct.

9e18fb7e90 Round Z in the vertex shader to match a 16-bit Z buffer. 
However this inexplicably does still not solve the Phantasy Star issue!

42bcea7b41 Report when minz/maxz is used in an effective way. 
As long as it's outside the viewport it should be clipped anyway.

One concern is, does clipenable affect z?  A game could depend on that.

5fa3bf0eb9 Move the viewport transform to the proj matrix. 
The viewport has an implementation defined maximum size.  On some devices,
it's as low as 2048 or 4096.

Tales of Destiny 2, for example, uses a large viewport, which may be
outside this range at 1x or 2x on such devices.  This makes it work much
better.  It may also have better subpixel precision.

08a1bb8796 Add support for ARM_shader_framebuffer_fetch. 2015-03-07 16:11:43 -08:00
Unknown W. Brackets
9c3ccc97a2 Support EXT_shader_framebuffer_fetch. 
We only supported NV_ before.  Not tested on any supporting device, but
this is primarily found on PowerVR devices.  This may allow them to
perform effects (like min/max/etc.) more accurately and quicker.

a3342a72d7 Fix copy/paste mistake from 808eeb3a25. 
I'm pretty sure this was not intentional.

b5126f7236 Use ONE/ZERO in place of CONSTANT_ALPHA if okay. 2015-02-23 09:58:46 -08:00

3ff51588f7 Avoid using constant color when blending. 
If it's just ONE/ZERO or etc., we can keep those constants.  May be
faster, and apparently less buggy in some drivers.

9d5ae2b336 For 5551 buffers, force stencil mask to 1/0. 
4444 it would also be ideal to spread the bits, but that gets a bit
complicated.  5650 probably doesn't matter.

4c15afa905 Allow multiple replacements on the same func. 
Or, more specifically, hooks.  This allows enter and exit on the same
func, which can obviously be useful for debugging.

c88b66b308 d3d9: Emulate some logic ops with blending. 
This makes Brave Story's intro visible.  Also add for GLES2/GLES3, but
doesn't seem to work on GLES2.

33ac30218a Bind the alphatest tex after we know vert alpha. 
Before we sometimes thought alpha test was trivially true when it wasn't.

94c1271761 Add an experiment with using a texture for tests. 
Using an option for now so it's easy to test, if it works well we can
maybe remove the option.

a43c3771a3 More correctly blend when hitting the frame cap. 
If we hit too many blits per frame, fall back correctly in the shader.

44620c92ed Premultiply for doubled alpha blending if possible. 
This makes the effect more accurate where the values were being clamped
before.  Some obscure methods of blending may be slower.

8d6a5fd694 Use correct stencil values with non-add blending.
