PFN_FunctionName is more readable than SCREAMSOUP_T.
Context creation API function typedefs are kept as-is where the original
header provided them, for compatibility and familiarity reasons.
If EGL_KHR_get_all_proc_addresses extension is supported, then don't try
to load a separate client library. Instead, just use eglGetProcAddress
to load everything.
This can also avoid problems with trying to use OpenGL functions from
libGL.so.1 (which is the GLX library) when an EGL context is current.
Closes#871.
Added GLFW_INCLUDE_VULKAN. Added glfwVulkanSupported,
glfwGetRequiredInstanceExtensions, glfwGetInstanceProcAddress,
glfwGetPhysicalDevicePresentationSupport and glfwCreateWindowSurface.
Added port of LunarG SDK tri example.
Removed compile-time selection of GLX entry point retrieval mechanism.
Made dlopen a required dependency.
This is a stopgap solution until we start requiring GLX 1.4.
The default behavior of WGL, EGL and GLX is to choose a config that has
/at least/ the specified number of bits, whereas the GLFW 2 behavior was
to choose the closest match with very few hard constraints. Moving the
responsibility of finding the supported minimum values to the client was
problematic, as there's no way to enumerate supported configurations,
forcing the client to perform multiple (and slow) window/context
creation attempts. Not even the currently set defaults (24-bit color
and depth, 8-bit stencil) is universally supported, as bug reports show.
Renamed _glfwLibrary to _glfw and made all substructs lower-case, making
global variable names easier to read and type. Partially inspired by the
internal naming conventions of glwt.
