| | | | | | | | | | | | It seems forcing points outside the cardioid and bulb with a bad random generator can take really long... Also, now framerate adjusts based on time it takes to render frames.

* Split buffer in three, one per color (as OpenGL guarantees that one can at ↵Andreas Grois2018-03-112-10/+26
| | | | | | | | least have 8 SSBOs), to allow three times larger images. Also make it possible to ignore maximum buffer size reported by the driver. The maximum buffer size limitation is rather strict on radeonsi, so I decided to split the buffer in three, effectively increasing the maximum image size by a factor of three. While doing so I realized that at least on radeonsi the reported maximum buffer size seems to be off. For this reason I added a new command line switch, that allows to ignore the maximum buffer size check. For those curious: radeonsi reports a maximum buffer size of 128 MB, but I had no problems when using three buffers of 1098 MB each.
* Instead of using the yDecoupler value directly, the code's now using theAndreas Grois2018-03-111-1/+1
