    <p>OpenGL isn't deprecated, <em>Microsoft's implementation of it is</em>. Microsoft's implementation is stuck at version 1.1, which <em>is</em> old. The current version of the standard is past version 4. If you want to use OpenGL, it is fully supported by <a href="https://developer.nvidia.com/opengl">NVidia</a>, <a href="http://developer.amd.com/tools-and-sdks/graphics-development/">ATI</a>, and <a href="http://www.intel.com/support/graphics/sb/CS-033757.htm?wapkw=opengl">Intel</a> graphics cards on the Windows desktop, but not in <strike>Metro</strike> Windows Modern UI apps, <a href="https://www.opengl.org/">is an industry standard,</a> and also works on <a href="https://developer.apple.com/opengl/">Mac</a> and Linux. If you need a software fallback implementation, <a href="http://www.mesa3d.org/">Mesa</a> has got you covered, and it <a href="https://www.youtube.com/watch?v=vkUwT9U1GzA">even works on DOS.</a> (Since Mesa can render into memory buffers, there's no reason it won't work in Modern UI apps, but you probably don't want to do this because it can be slow.) One thing of note is that WGL, the API for accessing OpenGL functionality on the Windows desktop, depends on GDI (which <em>is</em> deprecated) so you probably want to use something like <a href="http://freeglut.sourceforge.net/">FreeGLUT</a> or <a href="http://www.libsdl.org/">SDL</a> instead if you want to future-proof your application, which also nets you platform independence.</p> <p><a href="https://www.khronos.org/opengles/">OpenGL ES</a> is a variant of OpenGL which works on <a href="https://developer.android.com/guide/topics/graphics/opengl.html">Android</a> and <a href="https://developer.apple.com/library/ios/#documentation/3DDrawing/Conceptual/OpenGLES_ProgrammingGuide/Introduction/Introduction.html">Apple iOS.</a> It is also accessible in JavaScript via <a href="https://www.khronos.org/webgl/">WebGL</a>, <a href="http://www.engadget.com/2013/06/26/internet-explorer-11-to-support-webgl-and-mpeg-dash/">which Internet Explorer 11 will support</a> (<a href="https://www.khronos.org/webgl/wiki/Getting_a_WebGL_Implementation">and pretty much every other browser already does.</a>) <a href="https://code.google.com/p/angleproject/">ANGLE</a> provides a hardware-accelerated implementation of GLES for Windows which piggybacks off of DirectX (version 9 or 11) and thus should work in Modern UI apps as well. <a href="http://www.mesa3d.org/opengles.html">Once again, Mesa's got the software implementation covered.</a></p> <p><strong>TL;DR: OpenGL is not only <em>not</em> deprecated, it is cross-platform, standard, and has tremendous momentum in the industry. GDI and GDI+, well, not so much.</strong></p>

    1. COWhat would be the new API to initialize OpenGL on Windows? If MS deprecates WGL (FreeGLUT and SDL also depends on WGL), will the initialization procedure involve driver-specific interfaces through COM? Then, we are back on DOS.

    2. COEGL is the standard way to initialize OpenGL ES on all platforms, and ANGLE supports it. WebGL in JavaScript will be supported by IE11. WGL is unfortunately the only way to initialiaze Desktop OpenGL on Windows, and while MS doesn't support it anymore, graphics vendors do. It's not nearly as bad as DOS as it's one API across graphics vendors. WGL itself isn't likely to disappear until MS kills the desktop, in which case Desktop OpenGL will be irrelevant anyways. Use OpenGL ES 2 unless you really need geometry shaders, which are the biggest thing missing compared to Desktop OpenGL and DirectX.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
