2017-09-01Cleanup usages of Mid(foo, 1), Right(1), and Left(1)chromium/3203Ryan Harrison
Mid(foo, 1) is equivalent to [foo], if all you want is the character. Similarly Left(1) is [0]. It is faster also, since it does not need to create intermediate strings. Right(1) is a touch more tricky, since it requires something like GetLength() ? [GetLength() - 1] : 0;. A new method, Last() has been added to perform this character extraction. Multiple call sites have been updated to use more efficient/simpler syntax. There are a number of call sites that use on these patterns, but based on the surrounding context we actually need/want a string, so they have not been modified.

2017-09-01Prepare for converting FX_STRSIZE int->size_tRyan Harrison
When turning on this conversion a number of typing issues and other nits where found in the code base that can be merged in without actually changing the underlying type. Landing these changes before the type change CL, since there is a high likelihood that the type change will need to be rolled back, since it is high risk.

2017-08-31Make FPDF_GetText stricter on inputsRyan Harrison
The current implementation of this function is problematic. It will attempt to memcpy to NULL. It will accept obviously wrong inputs like a negative start index. It will also accept -1 for the count, which in theory is the amount of space the buffer has allocated to it, so doesn't make sense, but instead an internal call will calculate the number of characters to get if the count is -1. This will them lead to the function attempting to call Left(-1) on a string, which is invalid. Ths documentation for this function mentions none of this behaviour, so I am removing it, since it is inconsistent/bad. The implementation should now more strictly meet defined API.
