First build every project in vio2sf.dsw. This will include the vio2sf project which will copy vio2sf.bin into all the plugin dirs.
Then build foo_input_vio2sf from vio2sf.sln. This plugin my be built in a newer msvc.
It has a dependency on vio2sf, which will then overwrite all vio2sf.bin in all directories with a vc9 version.
This is safe since it doesn't import any CRT DLL, and it probably runs a little faster.

1) gen.bmp has a generic window frame for plugins to use.
its format is similar to the minibrowser's.
In addition gen.bmp includes a font for the titlebar, in both
highlight and no-highlight modes. The font is variable width,
and it uses the first color before the letter A as the delimiter.
The no-highlight form of letter must be the same width as the
highlight form.
2) genex.bmp has button and scrollbar images, as well as some individual
pixels that describe the colors for the dialog. The button and
scrollbar images should be self explanatory (note that the buttons
have 4 pixel sized edges that are not stretched, and the center is
stretched), and the scrollbars do something similar.
The colors start at (48,0) and run every other pixel. The meaning
of each pixel is:
x=48: item background (background to edits, listviews etc)
x=50: item foreground (text color of edit/listview, etc)
x=52: window background (used to set the bg color for the dialog)
x=54: button text color
x=56: window text color
x=58: color of dividers and sunken borders
x=60: selection color for playlists
x=62: listview header background color
x=64: listview header text color
x=66: listview header frame top color
x=68: listview header frame middle color
x=70: listview header frame bottom color
x=72: listview header empty color
x=74: scrollbar foreground color
x=76: scrollbar background color
x=78: inverse scrollbar foreground color
x=80: inverse scrollbar background color
x=82: scrollbar dead area color
x=84: listview/treeview selection bar text color (active)
x=86: listview/treeview selection bar back color (active)
x=88: listview/treeview selection bar text color (inactive)
x=90: listview/treeview selection bar back color (inactive)

/*
Autoplaylist APIs
These APIs were introduced in foobar2000 0.9.5, to reduce amount of code required to create your own autoplaylists. Creation of autoplaylists is was also possible before through playlist lock APIs.
In most cases, you'll want to turn regular playlists into autoplaylists using the following code:
static_api_ptr_t<autoplaylist_manager>()->add_client_simple(querypattern, sortpattern, playlistindex, forceSort ? autoplaylist_flag_sort : 0);
If you require more advanced functionality, such as using your own code to filter which part of user's Media Library should be placed in specific autoplaylist, you must implement autoplaylist_client (to let autoplaylist manager invoke your handlers when needed) / autoplaylist_client_factory (to re-instantiate your autoplaylist_client after a foobar2000 restart cycle).

//! A constructor taking const dsp_preset&, initializing the DSP with specified preset data.\n

//! static bool g_get_default_preset(dsp_preset &); - retrieving default preset for this DSP. Return value is reserved for future use and should always be true.\n
//! static GUID g_get_guid(); - retrieving GUID of your DSP implementation, to be used to identify it when storing DSP chain configuration.\n
//! static bool g_have_config_popup(); - retrieving whether your DSP implementation supplies a popup dialog for configuring it.\n
//! static void g_show_config_popup(const dsp_preset & p_data,HWND p_parent, dsp_preset_edit_callback & p_callback); - displaying your DSP's settings dialog; called only when g_have_config_popup() returns true; call p_callback.on_preset_changed() whenever user has made adjustments to the preset data.\n

/*!
This service implements methods allowing you to interact with the Media Library.\n
All methods are valid from main thread only, unless noted otherwise.\n
To avoid race conditions, methods that alter library contents should not be called from inside global callbacks.\n
Usage: Use static_api_ptr_t<library_manager> to instantiate. \n
Future compatibility notes: \n
In 0.9.6, the Media Library backend will be entirely reimplemented to perform tracking of folder content changes on its own. This API will still be provided for backwards compatibility, though most of methods will become stubs as their original purpose will be no longer valid. \n
To keep your component working sanely in future foobar2000 releases, do not depend on functions flagged as scheduled to be dropped - you can still call them, but keep in mind that they will become meaningless in the next major release.
