 // Ostensibly, SkBlitter::BlitRect is supposed to set a rect of pixels to full
 // alpha. This becomes problematic when using compressed texture blitters, since
 // the rect rarely falls along block boundaries. The proper way to handle this is
 // to update the compressed encoding of a block by resetting the proper parameters
 // (and even recompressing the block) where a rect falls inbetween block boundaries.
 // PEDANTIC_BLIT_RECT attempts to do this by requiring the struct passed to
 // SkTCompressedAlphaBlitter to implement an UpdateBlock function call.
 //
 // However, the way that BlitRect gets used almost exclusively is to bracket inverse
 // fills for paths. In other words, the top few rows and bottom few rows of a path
 // that's getting inverse filled are called using blitRect. The rest are called using
 // the standard blitAntiH. As a result, we can just call  blitAntiH with a faux RLE
 // of full alpha values, and then check in our flush() call that we don't run off the
 // edge of the buffer. This is why we do not need this flag to be turned on.

 // This class implements a blitter that blits directly into a buffer that will
 // be used as an compressed alpha texture. We compute this buffer by
 // buffering scan lines and then outputting them all at once. The number of
 // scan lines buffered is controlled by kBlockSize
 //
 // The CompressorType is a struct with a bunch of static methods that provides
 // the specialized compression functionality of the blitter. A complete CompressorType
 // will implement the following static functions;
