evas: font glyphs texture garbage collector
Summary:
Introduce two public APIS
```
#define EVAS_FONT_DATA_CACHE_TEXTURE 0x01
/**
* Set the limit in bytes for memory allocated by font glyphs in evas.
* @param[in] bytes cache size in bytes, pass negative value to ignore the limit.
* @param[in] options for caching, pass 0x1 to set the texture cache (in case of accelerated rendering).
*
* @since 1.24
*/
EAPI void evas_font_data_cache_set(signed long long int byte, int options);
/**
* @}
*/
/**
* Get the limit in bytes for memory allocated by font glyphs in evas.
* @param[in] options for caching, pass 0x1 to get the texture cache (in case of accelerated rendering).
* @return Returns font allocated memory cache limit, if value is negative this means no limit.
* @since 1.24
*/
EAPI signed long long int evas_font_data_cache_get(int options);
```
Test Plan:
elementary_test => Text Memory
You need a tool to observe Video memory allocation.
1- If you have detected Graphics card then use **radiontop** or **nvidia-smi** ).
2- If you have Integrated Graphics card, then you can detect memory allocation on RAM use.
----------------------------------------------
this example allows only 50 MByte Video memory texture allocated by font glyphs
