2017-09-14Revert moving JPX library decode from Init to DecodeRyan Harrison
Due to some of the size parameters for allocating space in Decode() depending on the values produced by opj_decode(), this change was causing misallocation of space, which in turn was causing illegal reads/writes.

2017-09-13Change behaviour of FPDF_RenderPageBitmapWithMatrixNicolas Pena
This CL changes the behavior of FPDF_RenderPageBitmapWithMatrix so it transforms the bitmap. Before, the page would be transformed and the assumption was that it would be drawn on a bitmap with the same dimensions as the original page. This does not work well because a transformation generally changes the dimensions of the page. The rectangles test is modified to include small rectangles in the corner of the page, so that it's clear that the whole original page is being displayed.

2017-09-13Rewrite IsHyphen using string operationsRyan Harrison
The existing code did end of range checks by making sure that the value was never less then 0. This isn't correct when using an unsigned type, since 0 - 1 will wrap around to the max possible value, and thus still be less then 0. Additionally the existing code was hard to follow due to the complexity of some of the low level operations being performed. It has been rewritten using higher level string operations to make it clearer and correct.

2017-09-08Move decompressing of JPX out of Init and into DecodeRyan Harrison
In the existing implementation of the JPX decoder, Init extracts the header from the image and then immediately decompresses it. This is problematic if it is a very large image that we won't be able to allocate a bitmap for. The code has been changed to instead delay decompression until the Decode method, since things like dest Bitmap generation can be performed using just the header information. There is also a bit of renaming/casting cleanup, because I was having a hard time parsing what was a local vs member variable.
