fixed from PVS-Studio

[ip-gpu]

I'm a member of the Pinguem.ru competition on finding errors in open source projects. A bug, found using PVS-Studio. Warnings:

V542 Consider inspecting an odd type cast: 'wchar_t *' to 'char *'. application.cpp 101

m_coeffs changed size to [SPLINE_POINTS][4]; V557 Array overrun is possible. The 'n' index is pointing beyond array bound. spline.h 27 V557 Array overrun is possible. The value of 'i' index could reach 15. spline.h 37 V557 Array overrun is possible. The value of 'j + 1' index could reach 15. spline.h 41 V557 Array overrun is possible. The value of 'j + 1' index could reach 15. spline.h 42 V557 Array overrun is possible. The 'ArcLengthIntegrandSingleSpline' function processes value '15'. Inspect the first argument. Check lines: 78, 92. spline.h 78

V575 The potential null pointer is passed into 'memset' function. Inspect the first argument. image_read.cpp 3495 V592 The expression was enclosed by parentheses twice: ((expression)). One pair of parentheses is unnecessary or misprint is present. spline.h 18 V728 An excessive check can be simplified. The '(A && !B) || (!A && B)' expression is equivalent to the 'bool(A) != bool(B)' expression. tga.c 309 V773 The function was exited without releasing the 'hFind' handle. A resource leak is possible. platform_win32.cpp 166, 185V773 The function was exited without releasing the 'tga_data' pointer. A memory leak is possible. image_read.cpp 2970
