GRAPHICS: Reset GL's current color in drawDimPlane()

Browse source 
Per convention, in residualvm the default GL current color
should be (1.0f, 1.0f, 1.0f). If a function changes the color,
it is required to reset it before returning.

This fixes the issue that some videos were not correctly displayed
until the next glColor call (e.g. when drawing the sub-titles) was
issued.
