+// Unicode in GLFW for DOS
+// =======================
+//
+// Keyboard mapping tables in GLFW for DOS use Unicode encoding. The codes
+// are 16-bit unsigned integers, and thus do not cover the entire Unicode
+// standard (but a great deal is covered).
+//
+// Keys or characters that are not supported by GLFW (for instance the
+// PrtScr or Windows keys that are found on most PC keyboards) are coded
+// with 0xFFFF ("not a character" according to the Unicode standard).
+//
+// GLFW special keys, as defined in glfw.h (e.g. GLFW_KEY_LSHIFT) are
+// encoded in the private area of the Unicode standard (i.e. codes in the
+// range E000-F8FF). The encoding is as follows:
+//
+//   unicode = 0xE000 + glfw_key - GLFW_KEY_SPECIAL;
+//
+// Every key in the keyboard matrix has a description consisting of four
+// entries: Normal, Shift, Caps, and AltGr.

+// Description:
+//
+// This module acts as an interface for different image file formats (the
+// image file format is detected automatically).
+//
+// By default the loaded image is rescaled (using bilinear interpolation)
+// to the next higher 2^N x 2^M resolution, unless it has a valid
+// 2^N x 2^M resolution. The interpolation is quite slow, even if the
+// routine has been optimized for speed (a 200x200 RGB image is scaled to
+// 256x256 in ~30 ms on a P3-500).
+//
+// Paletted images are converted to RGB/RGBA images.
+//
+// A convenience function is also included (glfwLoadTexture2D), which
+// loads a texture image from a file directly to OpenGL texture memory,
+// with an option to generate all mipmap levels. GL_SGIS_generate_mipmap
+// is used whenever available, which should give an optimal mipmap
+// generation speed (possibly performed in hardware). A software fallback
+// method is included when GL_SGIS_generate_mipmap is not supported (it
+// generates all mipmaps of a 256x256 RGB texture in ~3 ms on a P3-500).

+
+/*
+ * This module converts keysym values into the corresponding ISO 10646
+ * (UCS, Unicode) values.
+ *
+ * The array keysymtab[] contains pairs of X11 keysym values for graphical
+ * characters and the corresponding Unicode value. The function
+ * _glfwKeySym2Unicode() maps a keysym onto a Unicode value using a binary
+ * search, therefore keysymtab[] must remain SORTED by keysym value.
+ *
+ * We allow to represent any UCS character in the range U-00000000 to
+ * U-00FFFFFF by a keysym value in the range 0x01000000 to 0x01ffffff.
+ * This admittedly does not cover the entire 31-bit space of UCS, but
+ * it does cover all of the characters up to U-10FFFF, which can be
+ * represented by UTF-16, and more, and it is very unlikely that higher
+ * UCS codes will ever be assigned by ISO. So to get Unicode character
+ * U+ABCD you can directly use keysym 0x0100abcd.
+ *
