APIs and tests for extracting bitmaps from image objects
Added FPDFImageObj_GetBitmap() that returns the bitmap of an image object, and a FPDFBitmap_GetFormat() that returns the format of a bitmap. * Fixed a small bitmap conversion bug in cfx_dibsource.cpp. * Enabled EmbedderTest::CompareBitmap() to support different formats of bitmaps. * Added an embedder test and a test PDF file with images of many different formats.
