Rendering of tiling pattern which has pattern matrix moving pattern cell far
away (e.g. /Matrix [ 0.96000 0 0 -0.96000 42.54000 245481.37900 ]) can fail on
allocation of memory (e.g. in CairoOutputDev).
I've prepared a patch which solves this issue by moving the pattern cell as
close to (0,0) as possible by integer number of cells in pattern matrix before
it is passed to tilingPatternFill().
Attached is page number 332 from a document where this can be reproduced
(<a href="https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/pdf/virtualization_deployment_and_administration_guide/Red_Hat_Enterprise_Linux-7-Virtualization_Deployment_and_Administration_Guide-en-US.pdf">https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/pdf/virtualization_deployment_and_administration_guide/Red_Hat_Enterprise_Linux-7-Virtualization_Deployment_and_Administration_Guide-en-US.pdf</a>).
