89f3f35c9f stbi__skip should return immediately if skipping zero bytes. 
Otherwise we might waste time or throw away state in the i/o callbacks.

d60594847e Reject images that are too large (as defined by the application). 
The BMP loader already had this hardcoded to (1 << 24) pixels, so this seems
like a good default to apply to all formats, but many apps will want to clamp
this much much lower.

It's possible to craft malicious but valid images that are enormous, causing
stb_image to allocate tons of memory and eat a ton of CPU, so locking these
to a maximum permitted size can save a lot of headaches in the wild.

98ca24b8c7 Turn several asserts into formal checks. 
There are several places where stb_image protects itself from bad data with
STBI_ASSERT macros, but if these are compiled out in release builds the code
will overflow buffers, etc, without warning. If they are left enabled, the
process will crash from assertion failures.

This patch attempts to leave the assertions in place that are meant to verify
the correctness of the interfaces (if the calling function was meant to pass
only 8 or 16 for bit depth, it's reasonable to assert that is accurate), but
changes asserts that are triggered by corrupt or malicious image file data.

Failed asserts were the majority of crashes during fuzzing; now all of these
cases safely report an error back to the calling app.
