#727 large textures crash, triggered by platform behaviour

[Jorge Fuente-Alba]

Build v0.98.9
Using large textures (tested in sprite and tiledbackground) seems to corrupt the .cap somehow, "run all" crashes but "debug all" doesn't.
Steps to reproduce and outcome of "run all"
-new directX game: works as expected
-insert box: works as expected
-set platform behaviour in box: works as expected
-insert sprite: works as expected
-doodle and save sprite texture: works as expected
-load large texture into sprite (tested with 640x1024, ATI9600XT 128Mb VRAM): crash
-crop large texture to small one: crash
-delete sprite object: crash
-remove platform behaviour from box: works as expected
-add platform behaviour to box: crash
