57409c3d15 stb_image.h: Improve stbi__tga_info() and stbi__tga_test() 
* for paletted images, .._info()'s comp should be based on the palette's
  bits per pixel, not the images bits per pixel (which describes the
  size of an index into the palette and is also checked now)
* make sure the color (map) type and the image type fields of the header
  are consistent (=> if TGA color type is 1 for paletted, the TGA image
  type must be 1 or 9)
* .._test() does some more checks and uses stbi__get16le() instead of
  stbi__get16be() - TGA is little endian.
* .._test() now always rewinds (sometimes it used to do only return 0;
  without rewinding)
* remove "error check" at the beginning of stbi__tga_load(), because
  all that is already tested in stbi__tga_test()

7453e1bfa4 stb_image.h: Support 15/16bit per pixel RGB(A) TGAs 
stbi__tga_* assumed that 16bit TGAs were Grayscale + Alpha.
However, if the TGA imagetype is not one of the gray ones, it's 16Bit
RGB data, with 5 Bits per channel. If the TGA image descriptor field
has alpha bits (the 3 least significant ones) set, the pixel's most
significant bit is for alpha: 1 for opaque and 0 for translucent.
Furthermore people claim that TGAs can also pretend to have 15bpp,
which is the same as 16bpp but definitely without alpha.

So 15/16bpp TGAs are now decoded to STBI_rgb(_alpha).
