3353eeb0c3 Fix IE9 test timeouts by using different pixel placeholder
IE9 seems to have occasional problems with decoding
the data protocol url used before (single pixel placeholder).

03c75a8648 Transformation caching during reprojection triangulation
This usually saves around 30-35% of transformation calls.

726bcbef83 Alternative reprojection triangulation strategy
The quads are now subdivided more granually (to 2 instead of 4), which
usually leads to reduced number of triangles and higher performance.

8ab197eba6 Optimize the reprojection by stitching the sources prior to rendering

0f408e341f Rename ol.source.Image#getImage implementations to #getImageInternal

while #getImageInternal is used to obtain the actual data.

f2f77091ad Handle tile sources without projection

tilegrid should be created).
