For quite a while this has been causing integer division to generate a warning as error, blocking shader compiling. This means probably no one has even been running D3D in debug builds...
I tried disabling the warning with a #pragma, but it doesn't seem to apply when this flag is used.
We need to explicitly round when converting colors from float to uint
because multiplying a normalized float by 255 might not result in a whole
number. (The exact result here may vary depending on your
drivers/hardware.)
Ideally, we shouldn't be using floating point here, but fixing that is a
much more complicated patch.
Fixes gxtest TEV tests using Intel HD 4000.
CreateInputLayout requires a shader as an input, but it only cares about
the signature; we don't need to recompute it for different shaders with
the same inputs.
Trying to use GetDepthMatrixProgram outside of
TCacheEntry::FromRenderTarget is a bad idea, so don't. Instead, use a
shader which only copies the input.
Fixes lens flare depth test in Twilight Princess. See

- remove unused variables
- reduce the scope where it makes sense
- correct limits (did you know that strcat()'s last parameter does not
include the \0 that is always added?)
- set some free()'d pointers to NULL
This option was known to break every second game and only boost a bit.
It also seems to be broken because of streaming into pinned memory and buffer storage buffers.
v2: also remove dlc_desc
We are used to render them out of order as long as everything else matches, but rendering order does matter, so we have to flush on primitive switch. This commit implements this flush.
Also as we flush on primitive switch, we don't have to create three different index buffers. All indices are now stored in one buffer.
This will slow down games which switch often primitive types (eg ztp), but it should be more accurate.
This "u32 components" is a list of flags which attributes of the vertex loader are present.
We are used to append this variable to lots of vertex generation functions, but some of them don't need it at all.
The usual way to handle this kind of request is to rise a flag which the gpu thread polls.
The gpu thread itself either generates the result or just write zeros if disabled.
After this, it rise another flag which says that this work is done.
So if disabled, we still have the cpu-gpu round trip time. This commit just returns 0 on the cpu thread
instead of playing ping pong...
