Removed glEnable (GL_TEXTURE_2D); and glDisable (GL_TEXTURE_2D); calls
completely
Removed redundant brackets

Added and removed newlines

Removed redundant newlines

(3 for each triangle, 2 triangles per particle)
Also inverted the statements in the if conditions checking cache_size to improve
readability

Thanks go to Michail Bitzes for porting Firepaint first,
as those plugins share a lot of code it made this job
here easy...

Removed redundant calculation of this rVal (random value), because rVal is being recalculated a few lines later before being used again

Made nE an unsigned int to begin with as optionGetEmitters () will just return u-int values from 1 to 10
No need to calculate MIN (10, optionGetEmitters ()) for the same reason

Showmouse: Limit particle life to 0.9490 to ensure that the emitters are able to follow the mousepointer, even at extreme settings

Added missing glEnable/glDisableClientState calls for GL_TEXTURE_COORD_ARRAY and GL_COLOR_ARRAY to make showmouse work with the new codebase (Credits and thanks for this patch go to launchpad user bitzesmichail)

Also initialize the member variables int x and y in the ParticleSystem::ParticleSystem (int n) and ParticleSystem::ParticleSystem () constructors

Problem: Editors like gedit and others will not recognize *.xml.in files as xml, so if opened there is no syntax highlighting making those files harder to read.
This commit fixes this by adding <?xml version="1.0" encoding="UTF-8"?> to all *.xml.in files in lp:compiz 

Serialization was a cool idea for handling the temp load/unload problem,
however the usecase these days does not often involve that in order
to justify its continued maintainence.

Reduced combined filesizes of Compiz' .png resources from 2.2MB to 1.5MB by recompression of those with Trimage Image Compressor.
This will decrease package size, downloading/loading/displaying times without changing appearance in any way, because png is a lossless format and this commit just optimizes compression and filesizes.
png files with higher compression take less time to display, not only because of reduced loading times, but also because deflation in memory finishes faster as decompression speed is largely uninfluenced by the compression level and thus decompression of better compressed png files is faster.
