SDL2_ttf-2.0.15-bp153.1.1

- Update to new upstream release 2.0.15
  * Text rendering functions now use the alpha component of the
    text colors.
  * Added support for characters greater than 0xFFFF (e.g. emoji)
    in the UTF-8 APIs.

- Update to version 2.0.14
  * Deprecated TTF_GetFontKerningSize() which takes font glyph
    indices and added TTF_GetFontKerningSizeGlyphs() which
    takes characters

- Update to version 2.0.13
  * Fixed bug rendering text starting with a glyph with negative starting offset
  * Fixed regression loading non-scalable fonts
  * TTF_GetFontKerningSize() gets kerning between two characters, not two glyph indices

- Improve package summary and description. Drop --with-pic which
  is enabled implicitly anyway, remove redundant Requires.

- Some metadata spruce-up: add current URLs, softer wildcarding
  in the files list, more robust make install call

- created package (version 2.0.0) - based on SDL_ttf package
