+// VST Plug-Ins SDK Linux ONLY Port
+// VSTGUIL: Graphical User Interface Framework for VST plugins on LINUX:
+//
+// Version: 0.1
+// Author: kRAkEn/gORe
+// Date: 2007/01/21
+//-----------------------------------------------------------------------------
+
+Todo List:
+
+- Fix multiple CParamDisplay objects not showed correctly (only the first is shown)
+- Update other controls from a single control->update (), usually params displays not updating while mouse drag
+- Fix fonts names and sizes (actually only fixed and courier)
+- COffscreenContext not working (add an internal GC different from the frame GC)
+- Fix COffscreenContext CopyFrom
+- Turn back on CViewContainer::bOffscreenDraw (actually turned off to see something)
+- Keep out MOTIF defines (now that IS the default)
+- Make CBitmap work on every kind of GC (not pFrame only)

+/*! @class CBitmap
+@section cbitmap_alphablend Alpha Blend and Transparency
+With Version 3.0 of VSTGUI it is possible to use alpha blended bitmaps. This comes free on Mac OS X and with Windows you need to include libpng.
+Per default PNG images will be rendered alpha blended. If you want to use a transparency color with PNG Bitmaps, you need to call setNoAlpha(true) on the bitmap and set the transparency color.
+@section cbitmap_macos Classic Apple Mac OS
+The Bitmaps are PICTs and stored inside the resource fork.
+@section cbitmap_macosx Apple Mac OS X
+The Bitmaps can be of type PNG, JPEG, PICT, BMP and are stored in the Resources folder of the plugin bundle.
+They must be named bmp00100.png (or bmp00100.jpg, etc). The number is the resource id.
+@section cbitmap_windows Microsoft Windows
+The Bitmaps are .bmp files and must be included in the plug (usually using a .rc file).
+It's also possible to use png as of version 3.0 if you define the macro USE_LIBPNG and include the libpng and zlib libraries/sources to your project.
