checkInternalFormat() was not properly checking that the Skia bitmap
color type matches the OpenGL format and type combination. In some
cases this would lead to visual artifacts (e.g. when a 565 type is
uploaded to a 4444 type), while in other cases it would cause reading
out of bounds (e.g. when uploading Alpha_8 with a GL_RGBA format).
Note that valid Bitmap formats are documented at
https://developer.android.com/reference/android/graphics/Bitmap.Config.html
checkInternalFormat() now also matches getInternalFormat() and
getType().
