* ccpr: Don't use flat interpolation when it is slowGravatar Chris Dalton2018-02-02

* Use int when possible to calculate atlas indices in shaders.Gravatar Jim Van Verth2018-01-26
| | | | | | | | | | | | | | | | | On certain iOS devices half has a mantissa of only 10 bits, which is not enough to perform the floating point trickery to get the lower bits out of the "texture coordinates". Instead we use int if available, and float if not available. Also re-enables multitexturing for iOS and adds a sample which stresses the issue, and a version of fontcache that tests multitexturing.
