Examples: Extracted gamepad code into ImGui_ImplGlfw_UpdateGamepads()…

…. Renamed matching Win32 function for consistency.

Added more link to nothing's oversample document. Spacing bits.

 If you have very large number of glyphs or multiple fonts, the texture may become too big for your graphics API.
 The typical result of failing to upload a texture is if every glyphs appears as white rectangles.
 In particular, using a large range such as GetGlyphRangesChineseSimplifiedCommon() is not recommended unless you
