Stelpainter: restore OpenGL state after drawText(). Fixed all relevant calls in other classes. Result should be fine now. Massive savings in OpenGL state switching!

e8966ec... by gzotti

a few fixes of inconsistent states, and addition of instrumentation to StelPainter to see how many state changes were avoided. drawText must definitely be fixed.

update plugins to the new scheme. Unfortunately, StelPainter::drawText() breaks some of the expected benefit.

ea25cba... by gzotti

Cached the most frequently switched OpenGL states for the main app (no plugins yet). It seems there is a speed boost :-)

avoid needless OpenGL state changes for Comets

Reduced OpenGL state switching for Meteors. (Sporadic and MeteorShower plugin). Instead of blend switches per meteor, use state switches per frame (sporadic) or at least per shower (plugin). Code is not cleaned up yet, but it works.

A few first attempts to reduce redundant GL state changes

Updating coding style for LocationDialog

Applying device pixel ratio to the pixmap, so that it displays correctly
on Mac's. I really do not think this should be needed, but, until we
get HiDPI images, it may be.

Fixed (most) warning issues from Coverity Scan. (I cannot find warning reason for one, left note there.)
