Those are the common formats, but rest of image loaders should also call this some day.

--------------------------
Changes in 1.9 (not yet released)
- Add checks for sane image sizes in some image loaders (so far: bmp, jpg, tga, png).
Thanks @sfan5 for the original patch (got modified a bit): https://github.com/minetest/irrlicht/commit/dbd39120e7ed8c0c97e48e2df62347627f3c1d42
- Add IImage::checkDataSizeLimit and make IImage getDataSizeFromFormat return size_t so image loaders can check if sizes are sane.
- Fix crash with large jpg files. Based somewhat on a patch in Minetest from sfan5 https://github.com/minetest/irrlicht/commit/594de9915346a87f67cd94e28c7933993efb5d3b
- COSOperator::getSystemMemory now returns some value on OSX (thought same for total and available).
