Jonathan Li 96c921c776 gsdx: Update DirectX end user runtimes URL
The old one isn't working. I don't think there's a URL that redirects to
whatever language the user is using (unless my browser settings are
wrong), so I've just used the English US URL.

willkuer 9245d3ed7e gsdx: RendererEnum
1. Add GS_Renderer Enum

Replace all instances of int/uint32 renderer identifier by a strongly
typed enum and appropriate casts.

Only instances in GS[*].cpp/h classes were touched. GPU[*].cpp/h classes
do not to follow the same convention.

2. Add default renderer according to OS

The default renderer is OS dependent (Win -> Dx9HW, others -> OGLHW).
Consequently one should always check againt the appropriate default
value on config load.

The old behaviour was only - if a at all - problematic if the respective
element in the gsdx.ini was missing and probably even then didn't create
issues. The current implementation is still more stable and does not
depend on the implementation of GS.cpp -> GetConfig()

The goal is to check the impact on game that have wrong RT content.

Gregory Hainaut 92553add8e gsdx-ogl: accurate date regression. Bad interaction between depth & DATE
In the DATE42 algo, first pass must find the primitive that write the
bad alpha value. If depth test is fail, alpha value won't be written therefore
you mustn't keep the primitive id.

In theory to ensure 100% correctness, depth would need to be fully executed
(currently depth write is disabled). However it requires to copy the depth buffer.
It is likely bad for the perf.

Avi Halachmi (:avih) cee0b795ee Recording: handle cancel (at the GS[dx] dialog) gracefully
Without this patch, if a user initiates a recording and then cancels at the GSdx
dialog, the audio was recording anyway, which is probably highly unexpected.

However, while probably highly unexpected, it could still be useful to record
only audio, but with this patch it's now impossible.

We can reconsider if it turns out that people are actually using this "feature",
though one might as well set the video setting to be very unobtrusive (very low
resolution/bitrate) such that it uses very little CPU.

Avi Halachmi (:avih) 4474d4391b GSdx: capture - print recomended resolution and DAR to the console
This is the internal resolution which GSdx uses and recording at this resolution
is optimal, i.e. without any dumb scaling, with all relevant pixels and without
redundant pixels.

The resulting clip still doesn't have the correct aspect ratio set, but that's
just a property which can be set to the clip afterwards, which is where the DAR
becomes useful. Since it's usually anamorphic, when muxing later with the audio
use the DAR to set the playback aspect ratio.

Jonathan Li d4f6894e1b gsdx: Fix custom resolution and minor cleanup
This fixes the following issues when custom resolution is selected.
 - When the width is smaller than the native resolution width, the
   texture cache targets are removed on every Vsync signal, causing a
   black screen issue.
 - The texture cache code needs a 1 returned for the custom resolution
   upscale multiplier or there'll be some really funny graphical issues.

It also removes unnecessary GetConfig (which I think unconditionally
does a a file read on Windows) calls if the width was increased - the
upscale multiplier is already stored, and the custom resolution width
and height calls are now unnecessary.

Also fix some whitespace issues.

Avi Halachmi (:avih) 54afd377ee GSdx: recording: Progressive: make the recorded clip play at full speed
Before this patch, when recording Progressive (frame) mode, it recorded all
the frames correctly but set the clip's fps property to 25/29.97, so when
played back it played at half the speed (but was fine when played at double speed).

This patch does not affect the number of frames recorded per second, but rather
only sets the resulting clip fps property to the correct one (double than before).

Also fixes a bug that in a non-managed window in progressive mode, the title
displayed "200%" speed when it should have displayed 100% speed.

Fixes #832

Gregory Hainaut 78569ee833 gsdx-ogl: redo properly the setup of texture format
* add lengthly comment to explain the format
* Likely reduce the number of shader permutation
* Avoid slow AEM (on GPU)

Expect regressions because TC needs some fixes

v2: fix palette mode

Gregory Hainaut 2430abed33 gsdx: potential division by zero
CID 146833 (#2-1 of 2): Division or modulo by zero (DIVIDE_BY_ZERO)
divide_by_zero: In expression this->m_width / this->m_upscale_multiplier, division by expression this->m_upscale_multiplier which may be zero has undefined behavior.

Gregory Hainaut 81e056e79a gsdx: always enable the boost queue
ifdef was for VS2010

GSThread.h is useless. I keep it for the transactional queue implementation

Gregory Hainaut ca9b5ce11d gsdx-ogl: move depth conversion shader
Add 2 new shaders:
* ps_main12: cast a 16 bit depth to a RGB5A1 color
* ps_main16: cast a a RGB5A1 color to a 16 bit depth

Shader might be used in future commit as it seems Silent Hill uses this
kind of format.

Fix tab/indentation too
