52f78d07b8 LibGfx/WOFF2: Ensure numTables is within expected range 
An error is now returned if `numTables` is zero or greater than 4096.
While this isn't explicitly mentioned in the specification, subsequent
calculations will be incorrect if the value falls outside this range.

e9be1bcd09 LibGfx/WOFF2: Reject fonts with a compressed size larger than 10MiB 
This prevents a potential OOM condition when the header is malformed.

af633523af LibGfx/WOFF2: Tolerate incorrect totalSfntSize in WOFF2 header 
The specification says that this value is for reference only, so we
should be able to load a file where this value is incorrect.
